You play a disposable test subject sent to retrieve lost cargo from 11 layers of an alien planet, with a fully simulated limb and cardiovascular system. It began as the free itch.io game Scav Prototype. **Q: When did Casualties: Unknown come out and how much is it?** Release 1.0 launched on Steam on November 9, 2026 for US$22.99; regional prices and sales vary, so check the Steam page. A free demo with layers 1 to 5 stays on Steam but is no longer updated. **Q: How many characters and endings are there?** Three characters (the Experiment, Milky and Dune), each unlocked by finishing a run with the previous one, and three endings: the bio-pod, escape and M.E.R.C. endings. **Q: Can you save in Casualties: Unknown?** Only between layers: at the bottom of a layer choose save and quit. Mid-layer you can type saveandquit in the console (the ~ key), which restarts you at the top of that layer but disables achievements.

In the drop pod, move the emergency light to your off-hand (Q), break the rubber floor for 2 plastic and craft a canteen, then 3 foliage bags (press F to favourite them). Explore sideways before going down, throw glowplant fruit into dark drops, bandage every wound, and use the full timer on layers 1 and 2 to prepare. Casualties: Unknown drops you into an alien pit as a disposable test subject with one job: find the lost cargo at the bottom. Press reviewers called it "Noita for furries, and oh so deliciously miserable". [Press] The core loop is simple: explore a layer, loot, craft, keep your body working, then go down. This page covers the first two layers. ## Before you start - Do the Basic Training course. You can bark (B) to skip parts of the First Aid course. - Pick a preset: Relaxed (120-minute layers, more loot) for a first run, or Tough, the default. See [run settings](https://casualtiesunknownwiki.com/run-settings/). - In settings you can turn off the pixel filter and film grain for clarity, and turn on auto-jump. ## Controls Default keys (community wiki; check your own key bindings) | Action | Key | | Move / jump | A D / Space | | Attack / use item | Left / right mouse | | Switch hands | Q | | Inventory / crafting | Tab / C | | Health view | R | | Throw | T | | Ragdoll (go prone) | X | | Favourite item | F | | Item labels nearby | hold Left Ctrl | | Expand description | Left Shift | | Bark | B | | Console | ~ | There is no official controller support; Steam Input layouts work best on a Steam Deck or Steam Controller. See the [FAQ](https://casualtiesunknownwiki.com/faq/#controller). ## The first ten minutes Drag materials into the crafting menu to see what they make. Screenshot: Orsoniks / Oro Interactive, from the Steam store page. - You land in a drop pod with an emergency light on your back. Move it to your off-hand (Q) and save its battery where you can. - Break the pod's rubber floor for 2 plastic. Drag plastic onto the crafting icon to see recipes. - Craft a canteen (2 plastic, 10 ml bio-chem, 1 rope). Glowplant fruit gives light and bio-chem. - Craft 3 foliage bags and favourite them (F), or the game can rip them into dressings. - Make a flimsy knife from scrap metal (traps drop scrap) and a makeshift digging tool; favourite the digging tool too. - Loot everything. Most items are useful or tradeable. ## Exploring safely - Go sideways first. Sweep the layer in an S shape before dropping lower. - Light the drop. Throw a glowplant fruit down before you jump. It lights the floor and sets off traps. - Bait traps. Throw an item at jump pads and spike traps, then pass. Break the blocks under traps to disarm them. - Avoid flowing water. Break geysers near your path. - Climb back up by placing scrap metal as tiles, or throw items downward to boost yourself. - Hunt shade crawlers until you have 2 stiff carcasses for a makeshift helmet (INT 8). ## Keep the body working Keep hunger and thirst near 100. Drink from groundwater tiles and stop if you feel sick. Bandage every cut back above 80 skin health so it does not get infected. Keep a dressing and canvas on you. Sleep below 35% energy somewhere soft, and work out before sleeping to train Strength and Resilience. Low mood is dangerous, so eat good food and save naptails for bedtime. Full detail: [needs](https://casualtiesunknownwiki.com/survival-needs/), [medical](https://casualtiesunknownwiki.com/medical/), [mood](https://casualtiesunknownwiki.com/mood/). ## Use layers 1 and 2 to prepare The first two layers are the safest and have the most water and food. Players consistently advise using the full timer there. [Players] Before going to layer 3, aim to have: - Water in a canteen or bottles - 3 bags or a sling bag - Makeshift helmet - Wood sandals - Weapon - Dressings and canvas - Light source - Some food that keeps Read every E-PDA (35 INT XP) and blueprint (25 INT XP) you find. A PDA needs a battery: break a lightbulb, take its battery out with a wrench, power the PDA, read it, then take the battery back. Trade with survivors after washing and putting away guns. Next: [what to craft at each INT level](https://casualtiesunknownwiki.com/crafting/) and [what each layer throws at you](https://casualtiesunknownwiki.com/layers/). ## Questions **Q: Is Casualties: Unknown hard?** Yes. It is a slow survival simulator where small injuries become fatal if ignored, and runs are long. The Relaxed and Paradise presets make learning much easier; Paradise gives infinite last stands. **Q: Should I do the tutorial?** Yes, at least Basic Training. Since demo 6.1 the First Aid course unlocks after reaching layer 2 and the Crafting course after layer 3, so you learn the basics first. **Q: What are the controls?** A and D move, Space jumps, Q switches hands, Tab opens the inventory, C crafting, R the health view, T throws, X ragdolls, F favourites, B barks, Left Shift expands descriptions, Left Ctrl shows item labels and the ~ key opens the console. Check your settings: keys can be rebound. **Q: How long is a run?** Many hours. A layer takes 30 to 80 minutes depending on how much you loot. The In and Out achievement asks for an ending under 3 hours of in-game time, which only about 2% of players have. About these numbers. Thresholds and rates come from the community wiki, which reads them from the game code. Most were last verified on demo builds 5.1 to 7.0. Release 1.0 rebalanced some systems, so treat exact values as close, not exact. Where the 1.0 patch notes changed something, this page follows the patch notes.

The triage panel below gives the fix and items for each condition. Casualties: Unknown simulates the body in layers: each limb has skin health, muscle health, bleeding, infection, bone state and pain, and the whole body has blood volume, pressure, oxygen, heart rhythm, temperature and brain health. Most deaths start small. A cut that was never bandaged gets infected, the fever drains water, low blood volume drops pressure, and the heart begins to fibrillate. Treat early and treat the cause. ## Triage panel: pick a body part Tap a body part or a region button to filter. Each file lists the signs, the fix in order and the items to carry.

Above about 1 L/min, put a tourniquet on the limb, then bandage, then remove the tourniquet. See [bleeding](https://casualtiesunknownwiki.com/bleeding/). - Heart and oxygen. A fast-climbing heart rate or a ragged ECG is fibrillation. Shock it before it becomes cardiac arrest. See [heart and blood pressure](https://casualtiesunknownwiki.com/heart/). - Internal bleeding and hemothorax. Blood volume falling with no visible wound. Stop it, then drain the chest. See [internal bleeding](https://casualtiesunknownwiki.com/internal-bleeding/). - Blood volume. Inject a blood bag, Ringer's solution or saline, and keep eating: regeneration depends on hunger. - Infection. Disinfect any limb under 80 skin health before it becomes infected. See [infection and sepsis](https://casualtiesunknownwiki.com/infection/). - Bones, shrapnel and pain. These rarely kill on their own, but they stop you from moving and fighting. See [fractures and shrapnel](https://casualtiesunknownwiki.com/bones-and-shrapnel/). ## How to read the health panel The health panel: the body diagram in the middle, vitals and blood volume on the chip, moodles along the edge. Screenshot: Orsoniks / Oro Interactive, from the Steam store page. The panel is the in-game UNI-HEALTH chip. The body diagram shows icons on each limb: teardrops for bleeding (shown from about 0.018 L/min), cysts for infection (shown from 25%), a trembling joint for a dislocation, a broken bone for a fracture, and shards or rubble for shrapnel. A shaking limb is in pain. The chip shows heart rate, blood pressure and oxygen saturation (SpO2) with an ECG trace, blood volume, and the total bleeding rate under it. Release 1.0 added an opiate and venom display to the panel. Moodles sit around the edge. Many items work by dragging them from your inventory onto a limb in the panel, which starts a minigame for dressings, shrapnel, dislocations, amputation and defibrillation. In [Unchipped](https://casualtiesunknownwiki.com/run-settings/#unchipped) runs most numbers disappear and you read symptoms instead: speech, posture, shaking, screen effects and your character's comments. ## Pain, trauma and shock Total pain is the pain of your worst limb. It rises from falls, hits, traps, using a broken limb, fixing dislocations, pulling shrapnel and some items such as alcohol. Pain levels (community wiki, demo 5.1 to 7.0) | Moodle | Total pain | Effect | | Discomfort | > 10 | No effect | | Pain | > 30 | Red vignette, mood drops slowly | | Severe pain | > 55 | Strong vignette, slower movement | | Agony | > 80 | Near-blinding vignette, shock builds, ragdoll above 90 | Above 50 pain you also build trauma, which leads to the Scared (25) and Traumatized (45) moodles. Pain shock above 66% knocks you out. Limb pain above 60% stops you fixing dislocations or pulling shrapnel on that limb. Fix it: painkillers for small pain, morphine or fentanyl for big pain (watch the opiate overdose), and an ice pack, which speeds pain recovery by 150% and never runs out. Higher Resilience lowers pain overall: see [skills](https://casualtiesunknownwiki.com/skills/#resilience). ## Consciousness and passing out Consciousness is capped by the worst of several things: oxygen, blood pressure, pain, brain health, energy, temperature, radiation and sickness. If you keep fainting, look at which of those is low. Consciousness moodles | Moodle | Consciousness | Effect | | Confused | < 90% | Mild blur, slightly slower | | Very confused | < 72% | More blur and slowdown | | Fainting | < 55% | Strong blur, darker view, much slower | | Incapacitated | < 30% | Cannot act: no attacks, items, standing up or minigames | | Unconscious | < 20% | Out cold; energy recovers | | Concussed | head muscle < about 14% | Out until the head heals; head muscle heals 10x faster | Common one-shot knockouts: a stalactite or skullcrusher to the head, a coil shock, a sound cannon blast, a bear trap on the head, and explosions. A helmet is the best prevention. See [brain damage](https://casualtiesunknownwiki.com/brain-damage/). ## A medical kit worth carrying From the community getting-started guide, a full mid-game kit covers each failure mode once: - Sterilized dressing - Tourniquet - Blood bag - Bruise kit - Defibrillator (AED or manual) - Auto-pump - Epinephrine - L.R.D. or makeshift L.R.D. - Chest drain - Antiseptic in a spray bottle - Tweezers - Wrench - Ice pack - Painkillers or morphine Carry a wrench as well: batteries come out of devices with it, and a defibrillator without a charged battery is dead weight. Many crafted items need [Intelligence](https://casualtiesunknownwiki.com/crafting/) first. Version note. The September update and 1.0 made the game somewhat easier: some injuries are less debilitating, brain damage is less punishing and amputation is easier. [Official] ## Questions **Q: How do you heal in Casualties: Unknown?** There is no single heal button. Each injury has its own treatment: dressings for bleeding, an L.R.D. or procoagulant for internal bleeding, a chest drain for hemothorax, antiseptic for infection, a wrench for dislocations, a bone welding tool or splint for fractures, and defibrillators for the heart. Muscle and skin health also recover slowly while you eat well and sleep. **Q: What do the colours of the moodles mean?** Moodles are the round status badges. The badge colour and the highlight show how severe the condition is, and critical moodles keep their highlight even while you are unconscious. Hover a moodle in the health panel to read its description. **Q: Why is my character bleeding with no wound?** Blood volume falling with no teardrop icon on any limb usually means internal bleeding. Check the total blood-loss rate under the blood volume meter, then use an L.R.D., procoagulant or helluce. **Q: What is the heal console command?** Type heal in the console (the ~ key). It resets your medical state but does not undo amputations, neural booster use or the Hollow state. Since 1.0, using it outside the tutorial sandbox disables achievements. About these numbers. Thresholds and rates come from the community wiki, which reads them from the game code. Most were last verified on demo builds 5.1 to 7.0. Release 1.0 rebalanced some systems, so treat exact values as close, not exact. Where the 1.0 patch notes changed something, this page follows the patch notes.

If the limb loses more than about 1 L/min, put a tourniquet on it first, top up blood with a blood bag, Ringer's or saline, then bandage and take the tourniquet off. Eat well: blood only regenerates while you have hunger. ## How bleeding works Every injury can make a limb bleed: falls, traps, bites, shrapnel and cuts. Blood volume starts at 5 L. You lose mood as volume drops below 5 L, and your maximum oxygen falls faster and faster as it drops. Below 3 L oxygen capacity drops sharply, which leads to low blood pressure, fibrillation and cardiac arrest. Skin health limits how fast a limb can bleed. At 0 skin health a limb can bleed up to 1.8 L/min, at 50 skin health 0.9 L/min. Limbs without shrapnel slowly clot on their own, but a limb with shrapnel will not stop bleeding until you pull the shards or bandage it. The bandage minigame. Wrap the dressing around the limb in the health panel. Screenshot: Orsoniks / Oro Interactive, from the Steam store page. ## Dressings compared Bleeding treatments (community wiki item data, demo) | Item | What it does | How to get it | | Ripped dressing | Weak bleeding fix, crafting material | Rip canvas, bags or cloth | | Dressing | Slows bleeding about 0.034 L/min per use, +2.5 skin, -5.5 pain, small help to bones | 2 ripped dressings, crates, traders | | Sterilized dressing | Stops bleeding and disinfects the limb | Craft at INT 7 | | Plastic dressing | Stronger dressing | Titanium sheet recipe | | Medical suture | Treats bleeding directly | Loot, traders | | Clotting mush | Field clotting agent | Craft from blood | | Tourniquet | Pauses all bleeding on the limb and further out from the torso | Craft at INT 9 | Restoring skin health also lowers bleeding, which is why bruise kits and dressings both help. Dressings have no effect on muscle health. ## When to use a tourniquet Use a tourniquet when the total bleeding rate under the blood volume meter shows more than about 1 L/min, or when one limb has a dark brown teardrop. It pauses bleeding on that limb and any limb further from the torso. It cannot go on the torso, and on the head it stops your breathing. - It slowly causes up to 40 pain. - Natural healing on the limb almost stops while it is on. - After about 9 minutes, when the icon is fully red, muscle damage starts quickly. Take it off before then. ## Blood volume and getting blood back Blood slowly returns to 5 L at a rate tied to hunger: 0.0525 L/min at 100 hunger, slower as hunger falls, and nothing at 0. That makes food part of blood loss treatment. Fluids work faster: Fluids for blood loss | Fluid | Use | Watch out for | | Blood bag (your own) | Best refill. Draw blood with an empty bag while healthy, ideally before sleeping (craft at INT 12) | Takes blood away when you fill it | | Ringer's solution | Volume and thirst | Can thin or clot blood depending on your viscosity | | Saline | Volume and thirst | Thins blood slightly | | Human blood | Volume | Can cause sepsis | Thin blood bleeds faster. Low blood viscosity increases the speed of every bleed: -50% viscosity means +50% bleeding speed. Injecting a lot of miscellaneous liquids lowers viscosity a little each time. Procoagulant raises it. [Community wiki] ## How fast can you bleed out? At 5 L, losing 1 L/min gives you about 2 minutes before you drop under 3 L, where oxygen and blood pressure start to collapse. At 0.2 L/min you have around 10 minutes. The electronic watch gives a bleed-out estimate, which 1.0 made slightly more accurate. A last stand restores blood volume to 3.75 L, but it only triggers once per run and depends on your mood: see [last stand](https://casualtiesunknownwiki.com/mood/#last-stand). ## Questions **Q: How do you make bandages in Casualties: Unknown?** The basic dressing is crafted from 2 ripped dressings, which you get by ripping canvas or other rippable items. A dressing weighs 0.9u while two canvases weigh only 0.2u, so carry canvas and one dressing, and craft more when needed. Sterilized dressing needs INT 7. **Q: How long can I leave a tourniquet on?** About 9 minutes. The icon fills red over time; once it is completely red it quickly damages muscle on the affected limbs. It also causes up to 40 pain. A tourniquet on the head causes respiratory arrest. **Q: How do I get more blood?** Blood regenerates towards 5 L on its own, at up to 0.0525 L per minute with a full hunger bar and not at all at 0 hunger. To refill quickly, inject a blood bag you filled earlier, Ringer's solution or saline. You can draw your own blood with an empty blood bag while healthy. **Q: Can I use human blood from a red blood bag?** Injecting human blood can cause sepsis, which fades slowly. Red blood bags are used for bio-terminals; transferring the red blood out leaves you a free empty blood bag. About these numbers. Thresholds and rates come from the community wiki, which reads them from the game code. Most were last verified on demo builds 5.1 to 7.0.

[How we source](https://casualtiesunknownwiki.com/about/#sourcing). ## Sources - [Community wiki] [Blood (volume, pressure, internal bleeding, viscosity)](https://scavprototype.wiki.gg/wiki/Blood) Scav Prototype / C:U wiki, checked 2026-09-21 - [Community wiki] [Injuries (limb and body statuses)](https://scavprototype.wiki.gg/wiki/Injuries) Scav Prototype / C:U wiki, checked 2026-10-03 - [Community wiki] [Guide: Getting started](https://scavprototype.wiki.gg/wiki/Guide:Getting_started) Scav Prototype / C:U wiki, checked 2026-07-09 - [Official] [v6.0 patch notes](https://store.steampowered.com/news/app/4576490/view/1830163047266090) Steam news, checked 2026-04-20 --- # Internal bleeding and hemothorax in Casualties: Unknown URL: https://casualtiesunknownwiki.com/internal-bleeding/ Sources checked: 2026-11-11 Short answer: Internal bleeding drains blood with no teardrop on any limb. Stop it with an L.R.D. or makeshift L.R.D., procoagulant, or helluce (layer 4 onward). Then use a chest drain on the chest to remove the hemothorax: each use removes 35 and the drain recharges over time. Do not thin your blood while it bleeds. ## Signs of internal bleeding - Blood volume drops but no limb shows a teardrop icon. - The total bleeding rate under the blood volume meter is higher than the limb icons explain. - The internal bleeding moodle, which appears at about 0.043 L/min and changes with severity. - Vomiting blood. Internal bleeding builds up a separate bloody-vomit timer. - Pain in the thorax and falling oxygen, from hemothorax. Internal bleeding is slower than a bad cut: it is capped at about 0.21 L/min, and extra severity makes it last longer instead of faster. The danger is that it does not stop on its own and fills your chest. ## How to stop internal bleeding Internal bleeding treatments | Treatment | Notes | | L.R.D. | Full tool, reusable with L.R.D. serum. Craft at INT 15. Also removes 12 venom. | | Makeshift L.R.D. | Craft at INT 10, uses L.R.D. serum (INT 11). The early-game answer. | | Procoagulant | Thickens blood and stops the bleed. Crafted from bunchunk (Fungal pools fungus) or found. Also clears strokes fast. | | Helluce | A plant from layer 4 onward. Eat it. | | Last stand | Cuts internal bleeding by 95%, once per run. | Avoid lowering blood viscosity while bleeding internally. Thin blood bleeds faster everywhere. [Community wiki] ## Hemothorax: blood around the lungs While internal bleeding is at or above the moodle threshold, blood builds up around the lungs at about 2.6 per minute (more if the bleed is worse). The health panel shows it as a yellow outline growing around the lungs. Hemothorax thresholds (community wiki) | Hemothorax | Effect | | Any | -0.3% max oxygen and -0.125 breaths/min per point, thorax pain | | 40 | Moodle appears: about -5 breathing rate and -12% max oxygen | | 70 | Moodle turns critical: about -8.75 breathing rate and -21% max oxygen | | 100 | Outline complete | | 200 | Breathing stops | Fix: stop the bleed, then use a chest drain on the chest. Each use removes 35 hemothorax and causes a little bleeding. The drain recharges by itself, so keep it. It is crafted at INT 12 and found in medical crates, drop capsules and life pod chests. ## Venom and toxicosis Some bites carry hemotoxin. Venom thickens the blood, lowers oxygen, slowly destroys blood and slows clotting. Above 20 venom, bleeding will not heal naturally, so bandage instead. Venom per bite (community wiki; cave ticks were cut 75% in demo 7.0) | Source | Venom | | Shade crawler bite | 20 | | Overgrown tick bite | 14 | | Cave tick bite | about 1 | | Eating a venom gland | 30 | Moodles: mild toxicosis above 2, toxicosis above 25, severe above 55, toxic crisis above 80. Venom wears off at about 0.1 per second. Antivenom removes 80 per 100 ml and was buffed in 1.0. An L.R.D. removes 12. Digestion crystal shards also reduce toxicosis since 1.0. [Official] Most of the time the practical answer is to wait it out while keeping blood volume up. ## Questions **Q: How do you get blood out of your lungs in Casualties: Unknown?** That is hemothorax. Only the chest drain removes it directly, 35 points per use, and it recharges after each use. Stop the internal bleeding first or it keeps refilling. A last stand also halves hemothorax. **Q: What causes internal bleeding?** Muscle damage to the head, thorax or abdomen from gunshots, explosions and falls, an abdomen below about 4% muscle health, radiation sickness above 9 Gy, and hard stimulants. **Q: Can I make an L.R.D.?** Yes. A makeshift L.R.D. needs INT 10 and L.R.D. serum needs INT 11. The full L.R.D. needs INT 15. Spare serum from duplicate L.R.D.s can be stored in an IV bag. **Q: Where is helluce?** The community guide lists helluce from layer 4 (Wasteland) onward. Eating it treats internal bleeding. Since 1.0 eating it also drops whatever you hold in your mouth. About these numbers. Thresholds and rates come from the community wiki, which reads them from the game code. Most were last verified on demo builds 5.1 to 7.0. Release 1.0 rebalanced some systems, so treat exact values as close, not exact.

[How we source](https://casualtiesunknownwiki.com/about/#sourcing). ## Sources - [Community wiki] [Blood (volume, pressure, internal bleeding, viscosity)](https://scavprototype.wiki.gg/wiki/Blood) Scav Prototype / C:U wiki, checked 2026-09-21 - [Community wiki] [Injuries (limb and body statuses)](https://scavprototype.wiki.gg/wiki/Injuries) Scav Prototype / C:U wiki, checked 2026-10-03 - [Community wiki] [Guide: Getting started](https://scavprototype.wiki.gg/wiki/Guide:Getting_started) Scav Prototype / C:U wiki, checked 2026-07-09 - [Official] [Release 1.0 patch notes](https://store.steampowered.com/news/app/4576490/view/1848664643355531) Steam news, checked 2026-11-09 --- # How to cure infection and sepsis in Casualties: Unknown URL: https://casualtiesunknownwiki.com/infection/ Sources checked: 2026-11-11 Short answer: Infection comes from wounds left under 80 skin health. Disinfect the limb with a sterilized dressing, or spray relief cream or antiseptic from a spray bottle (glowplant fruit works in a pinch), and keep immunity up by eating and staying warm. If total infection passes 100 you get sepsis; bring it back under 100 or amputate the worst limb. ## What causes infection Infections start mostly from cuts and injuries that drop skin health below 80. Being sick above 85 can also infect the abdomen, and radiation sickness above 9 Gy can start random infections. The infection grows in the limb and is revealed at 25%, as a moodle and a cyst icon that turns purple as it worsens. Your character shows faint green stripes, then purple ones, on the infected limb. A rose light shows infections earlier. Prevention is cheap: bandage every wound back above 80 skin health. That alone stops most infections. ## Infection stages Infection moodles (community wiki) | Moodle | Infection | Effect | | Infection | > 0% | The limb stops healing skin and muscle; pain grows at infection / 10 | | Painful infection | > 40% | Limb pain 4 or more | | Severe infection | > 60% | Pain 6 or more; muscle starts dying above 75% | | Life-threatening | > 80% | Pain 8 to 10; spreads to neighbouring limbs above 90% | Each infected limb also raises body temperature by 0.02°C per second up to 40.5°C, so a bad infection costs you water and can push you into [hyperthermia](https://casualtiesunknownwiki.com/survival-needs/#temperature). ## Disinfectants and how to make them Ways to disinfect a limb | Item | INT to craft | Notes | | Sterilized dressing | 7 | Stops bleeding and disinfects at once | | Spray bottle | 7 | Holds the liquids below | | Relief cream | 9 | Best spray; also eases pain | | Antiseptic | 9 | Standard spray | | Antiseptic mush | training recipe | From popskin; buffed in demo 7.0, fits in medkits | | Alcohol | found | Disinfects but hurts | | Glowplant fruit | found | Makeshift antiseptic | A disinfected limb is protected and its infection stops growing, unless your immunity is very low. Reapply as the effect wears off. [Community wiki] ## Immunity Immunity decides whether an infection shrinks or grows. It drops with hunger, cold, sickness (up to -80) and radiation, and rises with heat (up to a fever), antibiotics and a last stand. At 196% immunity every infection slowly clears by itself. ## Sepsis Sepsis builds when your total infection across all limbs is above 100: one 100% limb, or two 50% limbs. It also comes from injecting human blood (that kind fades by itself). Sepsis lowers blood pressure, stamina and maximum oxygen. Sepsis stages | Moodle | Sepsis | Effect | | Sepsis | > 10 | Up to -30% stamina, less oxygen, wakes you from sleep above 35 | | Severe sepsis | > 50 | About -36% max oxygen | | Septic shock | > 80 | -58% to -72% max oxygen; breathing stops above 99 | Fix: get total infection below 100 by disinfecting or amputating. Antibiotics and antiserum slow sepsis. A last stand cuts septic shock by 60%. Low pressure from sepsis can start fibrillation, so watch the [heart](https://casualtiesunknownwiki.com/heart/). ## Amputation Drag a blade onto an infected limb in the health panel to start the amputation minigame. Valid tools include the flimsy knife, crude cleaver, metal sickle, machete, titanium machete and titanium multitool. Side-to-side wobble hurts and causes bleeding. Afterwards the stump bleeds heavily, so have a dressing and tourniquet ready. Release 1.0 made amputation less punishing, allowed it on non-infected limbs, and allowed losing both legs. Lost limbs are no longer permanent: prosthetics come in 3 tiers, and the highest is better than a normal limb. Worn items on the limb drop instead of being deleted. [Official] [Official] ## Questions **Q: How do you make antiseptic in Casualties: Unknown?** Relief cream and antiseptic can be crafted from scratch at INT 9. Put either one in a spray bottle (INT 7) and spray the limb. Relief cream is the better of the two. Antiseptic mush, crafted from popskin, is a cheaper training recipe. **Q: Do glowplant fruits cure infection?** They work as a makeshift antiseptic and disinfect the limb, which helps when you have nothing else. They are also a light source you can throw. **Q: What is a good immunity level?** Normal immunity is 100%. At 196% and above every infection clears on its own, and the Leukocyte Overflow achievement needs 200%. Antibiotics, heat and good food raise it; cold, hunger, sickness and radiation lower it. **Q: Does amputation stop infection?** Yes. Cutting off a badly infected limb removes its infection from the total that drives sepsis. Since 1.0 you can amputate non-infected limbs too, and lost limbs can be replaced with prosthetics. About these numbers. Thresholds and rates come from the community wiki, which reads them from the game code. Most were last verified on demo builds 5.1 to 7.0. Release 1.0 rebalanced some systems, so treat exact values as close, not exact. Where the 1.0 patch notes changed something, this page follows the patch notes.

Fracture: use a bone welding tool early (it cuts the remaining heal time to a quarter) or a splint, then rest; untreated it takes about 39 minutes. Shrapnel and glass: click Remove shrapnel and pull slowly and straight, or use tweezers. ## Dislocations A dislocated joint shows a trembling joint icon, bends your posture and hurts whenever you use that limb, for example jumping on a dislocated leg. Bone injuries also cap that limb's muscle health at 50 until they heal. Ways to fix a dislocation | Method | Pain | Risk | | Bare hands (minigame) | +15 to +24 per push | 5% chance per push to fracture the limb (+100 pain, heavy bleeding) | | Wrench (minigame) | +5 to +10 per push | Low. The makeshift wrench and titanium multitool do not work | | Splint | None | Slow: +100% healing speed | | Bruise kit | None | Heals it directly | | Dressing | Lowers pain | Small heal per use | You can stop the minigame at any time; how close you got changes the severity. Painkillers before you start help you stay under the 75% pain limit. Mending a dislocation gives +3 mood. Special cases: a dislocated jaw hurts every time you eat (since demo 6.0 it makes food 25% less effective instead); a dislocated spine cuts swing damage by 40% and hurts as you move. ## Fractures A broken arm cannot hold items and hurts badly when you dig or hit. A broken leg hurts on every jump and landing. A head fracture usually breaks the neck (-40% attack damage, pain on attacks and jumps) and can disfigure you. Broken ribs cut swing damage by 40%. Fracture healing (community wiki, demo 5) | Treatment | Time to heal | | Nothing | About 39 minutes | | Splint | About 16 minutes | | Bone welding tool | Remaining time divided by 4 per use (best when used first) | | Dressing | Small boost per use | 39 minutes is a large part of a 60-minute layer, and you burn roughly 100 hunger and 140 thirst while waiting. Stock food and water before you risk big drops. In oil pools on layer 3, a broken leg can drown you. ## Shrapnel and glass shards Shrapnel comes from explosions, turrets and glass. A limb with shrapnel will not heal or stop bleeding naturally. Glass shards stuck in a foot show as glass in the body diagram; stepping on them gives 5 shrapnel, big skin damage, bleeding and a burst of pain. - Click Remove shrapnel above the icon. - Grab a piece and pull it straight out, slowly. Pulling too fast or too far sideways makes you let go: +9 to +16 pain, -5 skin, a bit more bleeding. - With tweezers (INT 9) there is no speed limit; only sideways wobble fails. - On the head, each failure has a high chance to cost a little brain health. Use tweezers there. - Bandage the limb afterwards. Shaky hands make this harder: low Resilience, pain and low consciousness all add wobble. Painkillers help if you lack tweezers. ## Prosthetics Release 1.0 added prosthetics, so losing a limb no longer ends the usefulness of a run. There are 3 tiers; the last tier is a straight upgrade over a normal limb. Prosthetics are repaired and maintained differently from flesh, not healed. [Official] [Official] ## Questions **Q: How do you fix a dislocation in Casualties: Unknown?** Open the health panel, click Fix dislocation above the joint icon and push the bone back into the outline with fast mouse swings. A wrench (INT 12 to craft) cuts pain per push to +5 to +10. Bare-handed each push hurts +15 to +24 and has a small chance to fracture the limb. You cannot do it above 75% total pain. **Q: How long does a broken bone take to heal?** About 39 minutes untreated in the demo code, about 16 with a splint. A bone welding tool divides the remaining time by 4, so use it right away. Healing a fracture gives +5 mood and unlocks the Good as New achievement. **Q: Do splints work?** A splint speeds fracture healing by 150% and dislocation healing by 100%, but it wears out while worn. The community guide calls it the weakest option; a bone welding tool and dressings are faster. **Q: How do you avoid glass shards?** Wear wood sandals (INT 8) or tactical boots (INT 16). Glass shards have a 40% chance to appear when you break a glass block, so watch where you step after breaking glass. About these numbers.

If the heart stops, put on an auto-pump and shock again: each successful shock has a 20% chance to restart it, or use epinephrine. ## Heart rate basics A healthy heart sits around 70 bpm and adjusts itself to hold blood pressure near 120/80. Pain, adrenaline, low stamina, heat, thick blood and fibrillation push it up; opiates and cold pull it down. Above 200 bpm fibrillation starts. Below 20 bpm the heart stops. ## Fibrillation Fibrillation is an abnormal rhythm that climbs about 1% per second while any cause is present, and 4% per second above 280 bpm (since demo 6.1). Each 1% adds 1 bpm and lowers breathing. At 60% the injury alarm plays and you hear your heartbeat outside the panel; at 100% the heart stops. What starts or feeds fibrillation (community wiki) | Starts it | Keeps it climbing | | Heart rate over 200 bpm | Heart rate over 200 bpm | | Blood pressure under 78/51 | Blood pressure under 88/58 | | Oxygen under 50% | Oxygen under 60% | | Core temperature under 28°C | Core temperature under 28.5°C | | Blood viscosity over 95 | Blood viscosity over 80 | | Stroke over 90, thirst over 175, 40 ml+ epinephrine, weight under 29.6 or over 70.4 kg | | Moodles: arrhythmia above 15%, ventricular tachycardia above 50%, ventricular fibrillation above 75%. A shock resets fibrillation to 0 but it comes back if the cause remains. Amiodarone lowers it over time. Touching a coil also resets it. ## Defibrillators: AED vs manual Defibrillator comparison | | AED | Manual defibrillator | | Works on fibrillation | Always | Only if the joules are close to right | | Speed | About 4 s analysis plus a 3.5 s charge | Faster, up to about 5 s charge at high power | | Battery | Uses more | 0.05% of a small battery per joule | | Shows vitals | No | Yes: heart rate, pressure, oxygen (useful in Unchipped) | | Cardiac arrest | 20% chance per successful shock, any power | Use either on the upper torso. Both start a minigame. Always check the battery first: players often find their AED empty at the worst moment. A wrench takes batteries out. The rule from the community wiki: the right power is twice the fibrillation percentage. Each joule off costs 2.5% success, and 40 J or more off never works. The device shows an estimated range that narrows with INT: about 140 J wide at INT 10, 90 J at INT 15, 0 to 10 J at INT 23 or more. Restart the minigame to reroll the estimate and intersect the ranges. [Community wiki] ## Cardiac arrest A flat ECG, 0 bpm and the dying drone. Without circulation, brain health falls fast. If you are still conscious: - Put on an auto-pump: it pumps blood when pressure gets low and keeps oxygen moving. - Shock with a defibrillator. Any power works for arrest; use low power to save battery. Each successful shock has a 20% chance to restart the heart. - Or take epinephrine: each tick has a 3% chance to restart the heart (at 50% fibrillation). Injected epinephrine lasts 6 ticks per ml, drunk 1. Too much (over 240 ticks) makes fibrillation worse. - Once restarted, shock again if needed to clear the fibrillation, then fix the cause. Restarting a stopped heart unlocks Dead Man Walking, one of the rarest achievements at about 1.5% of players. ## Blood pressure Blood pressure moodles | Moodle | Pressure | Effect | | Hypertensive crisis | > 180/119 | 2% stroke chance per second, big consciousness and breathing loss | | Severe hypertension | > 162/107 | Head pain, slower breathing | | Hypertension | > 145/96 | Headache, nosebleed above 155/102 | | Mild hypertension | > 130/86 | Slight consciousness cap | | Mild hypotension | < 110/73 | Slight dizziness | | Hypotension | < 96/63 | Pale; fibrillation climbs under 88/58 | | Severe hypotension | < 83/55 | Fibrillation starts under 78/51 | | Circulatory collapse | < 60/40 | Consciousness 0, organs starve | What moves pressure: blood volume (the biggest factor), viscosity, heart rate, temperature (3/2 per °C away from 37), thirst above 100 or below 40, weight, opiates (lower), sepsis (lower), vasopressin (higher) and sodium nitroprusside (lower). ## Stroke A stroke is bleeding in the brain. It starts with a 2% chance per second while systolic pressure is over 180, or rarely from eating a browncap, then grows by about 8 per minute. Each point costs blood and brain health. - Above 20: stuttering speech. - Up to about 50: the left arm weakens, then becomes unusable; you lose vision behind you. - Above 50: the health panel button flashes. Above 70: the moodle finally appears. - Above 90: fibrillation is forced. Fix: any amount of braingrow clears a stroke over 100 seconds. Procoagulant reduces it fast. A neural booster, mindwipe or last stand sets it to 0. Then bring your pressure down so it does not happen again. ## Pulmonary embolism With blood viscosity above 90 you can develop a pulmonary embolism, which damages the thorax muscle until lung failure in about 2 minutes 40 seconds from full health. A bruise kit or L.R.D. buys time. It ends once viscosity drops below 50. In Unchipped you only notice it from dialogue or the fur on your chest. ## Questions **Q: How do you do CPR in Casualties: Unknown?** There is no CPR in single-player. You restart a stopped heart with a defibrillator (20% chance per successful shock, any power) or epinephrine, while an auto-pump keeps oxygen moving. The community notes that the multiplayer mod adds CPR at about 100 compressions per minute. **Q: How do you lower blood pressure?** Find the cause: overdrinking (thirst above 100), being cold, high blood viscosity, high weight or stimulants. Warm up, stop drinking, wait for thick blood to settle, or inject sodium nitroprusside, which lowers pressure by up to 30/20. **Q: How do you raise blood pressure?** Restore blood volume, treat sepsis, cut back on opiates and warm up if you are hot. Vasopressin raises pressure by up to 30/20. **Q: What does blood viscosity do?** It is a hidden value. Thick blood (positive) raises pressure, can cause pulmonary embolism above 90 and fibrillation above 80 to 90. Thin blood (negative) speeds up every bleed. Both reduce max oxygen beyond plus or minus 40. It drifts back to 0 at 3 per minute. About these numbers. Thresholds and rates come from the community wiki, which reads them from the game code.

It heals slowly (about 11% per hour). Braingrow repairs it in small doses only, and a neural booster helps once. Prevention matters most: wear a makeshift helmet, then a bicycle or riot helmet, and avoid low oxygen and heatstroke. ## What damages the brain - Head trauma. Stalactites, skullcrushers, falls onto your head, turret and spike hits to the head. - Low oxygen. Brain health starts falling below 80% SpO2 and much faster below 60%. Cardiac arrest drains it quickly. - Heat. Heatstroke above 41.5°C body temperature; 0.5% per second above 42°C. - Radiation, from the first gray, plus random 10-point hits above 9 Gy. - Opiate overdose and stroke. - Water intoxication (thirst above 175). Brain health also caps consciousness: at 60% brain health you can never be more than 60% conscious. ## Stages Brain health moodles (community wiki; 1.0 spreads some effects to lower thresholds) | Moodle | Brain health | What happens | | Cognitive impairment | 95% to 80% | Mild distortion, confused talk, tastes metal, minor garbled text | | Neurological damage | 80% to 60% | Heavy distortion, incoherent speech, hard-to-read text | | Severe neurophysiological deterioration | 60% to 30% | Violet distortion, speechless under 50% | | Comatose | under 30% | Incapacitated, text unreadable | Low consciousness and brain damage blur and darken the whole screen. Screenshot: Orsoniks / Oro Interactive, from the Steam store page. Below 95% you can randomly shake and ragdoll, get mirrored controls (the screen flips to match), see flashes, vomit (33% every 30 seconds) and hear combat music that is not there. In 1.0 several of these only trigger at progressively lower brain health, so mild damage is less disruptive than in the demo. [Official] ## Braingrow, neural booster and mindwipe Brain repair options | Item | Effect | Catch | | Braingrow | Repairs brain health; clears a stroke over 100 s | 50% vomit chance, braingrow sickness, overdose risk. Small doses only. | | Neural booster | +10 brain health and +20 mood on first use; clears stroke | INT 18 to craft. A second one makes you vomit and overheat. | | Mindwipe | +50 brain health, stroke to 0 | INT to 0, permanent Hollow | | Rest | About 0.18% per minute, 11% per hour | Slow; not after a mindwipe | | Last stand | Sets brain health to 75 to 90% | Once per run, mood-dependent | Hollow trap. Taking braingrow or a neural booster within 20 minutes of a mindwipe or neural booster makes you Hollow too. [Community wiki] ## Helmets and prevention - Hunt shade crawlers on layers 1 to 3 until you have 2 stiff carcasses, then craft a makeshift helmet at INT 8. The community guide calls it top priority. - Upgrade to a bicycle helmet at INT 13. - Upgrade to a riot helmet at INT 17. - Throw a glowplant fruit into dark drops before jumping, and look up for stalactites in the Dried desert and Wasteland. ## Questions **Q: Does braingrow increase intelligence?** No. Braingrow only repairs lost brain health and clears strokes. It does not raise INT. It has a 50% chance to make you vomit and overdosing is dangerous, so use small doses. **Q: What is cognitive impairment?** The first brain damage moodle, between 95% and 80% brain health: mild visual distortion, confused speech, occasional erratic behaviour and some garbled text. **Q: What does mindwipe do?** It is a last resort. After a painful sequence it gives +50 brain health and clears strokes, but sets INT to 0 and makes you permanently Hollow: black and white vision, no speech, mood stuck near 0 and worse trader reputation. **Q: Which helmet is best?** Makeshift helmet (INT 8, needs 2 stiff carcasses from shade crawlers), then bicycle helmet (INT 13), then riot helmet (INT 17). None gives full immunity to stalactites. About these numbers. Thresholds and rates come from the community wiki, which reads them from the game code.

Raise it with good food, sleep, naptails, trading with or hugging friendly survivors, plushies and relief or soothing crystals, and fix what drags it down: pain, hunger, thirst, cold, wetness and bleeding. Keep it above 10: your last stand chance is set by your mood 9 to 10 minutes before you nearly die. ## What raises and lowers mood Mood influences (community wiki) | Raises mood | Lowers mood | | Good-tasting food and drinks | Bad-tasting food, raw meat | | Being satiated or full | Hunger and thirst under 40 | | Sleeping; waking after a naptail | Pain, trauma, sickness over 20% | | Trading with or hugging a friendly survivor | Unfriendly survivors; threatening or killing one | | Mending a dislocation (+3) or fracture (+5) | Bleeding, low blood volume | | Holding a relief or soothing crystal shard | Being too hot or too cold, wetness | | Opiates and antidepressants (temporary) | Corpses (less each time), radiation, hearing loss, withdrawal | Mood drifts back towards 0 at about 0.45 per minute when positive and 0.6 per minute when negative, and faster while asleep (demo 7.0). Runs start between -10 and 10. Release 1.0 buffed the soothing crystal shard. [Official] ## What low mood does Mood moodles | Moodle | Mood | Effect | | Gleeful | > 80 | Last stand guaranteed | | Happy | > 50 | Big last stand bonus (guaranteed above 70) | | Excited | > 30 | Better last stand chance | | Satisfied | > 10 | Slightly better last stand chance | | Feeling down | < -10 | Actions start to fail; slower acceleration under -20 | | Gloomy | < -30 | Last stand can no longer trigger | | Depressed | < -50 | Mindwipe usable; risk of self-harm episodes under -70 | | Miserable | < -75 | Cannot use non-opiate items in the health panel | Negative mood also makes you need sleep more often (up to twice as often at -100) and hides the hunger warning until you are hungrier. The chance an action fails rises from 5% at -10 to 15% at -30, 36% at -50 and 90% at -100. Self-harm. Below -70 the character can have episodes that injure them. Moving around or falling asleep can stop an episode before it starts, and holding a plushie can end it harmlessly. The fastest fix is to stop the mood falling: eat, sleep, treat pain. The game offers Censor mood and Censor pain settings. ## Last stand calculator Last stand is a once-per-run rescue. It is rolled when brain health falls under 15 while you are still alive, using your mood from 9 to 10 minutes earlier. Instant head deaths (gunshots and spike traps to the head) can skip it. The curve comes from points the developer shared: 0% at -30 and below, 10 to 20% around -10, 20% at 0, 50% at 10, 100% at 70 and above. Values in between are interpolated. [Community wiki] What it does: brain health set to 75 to 90%, blood to 3.75 L, oxygen to 100%, heart rate to 120, fibrillation, stroke and embolism cleared, internal bleeding and limb bleeding and infection cut by 95%, hemothorax halved, radiation and septic shock cut, energy full, temperature back to 37°C, and 5 minutes of adrenaline. Since demo 7.0 it also sets mood to about 10, and since 1.0 it lowers dirtiness. The death screen adds ", yet hopeful" after a survived last stand. The Paradise preset gives infinite last stands. See [run settings](https://casualtiesunknownwiki.com/run-settings/). ## Questions **Q: How do you increase mood in Casualties: Unknown?** Eat good-tasting food (geofruit is a reliable early one), stay satiated, sleep, eat a naptail before sleeping, trade with or hug friendly survivors, mend bones, carry a plushie and hold a relief or soothing crystal shard. Opiates and antidepressants help temporarily. **Q: How do you distract yourself from low mood?** The game's hint means doing things that lift mood: eat something good, sleep, talk to or trade with a survivor, or hold a plushie or crystal shard. Fixing pain, hunger, thirst, cold and wetness stops further drops. **Q: How does last stand work?** Once per run, when brain health drops below 15 while you are still alive, the game rolls a chance based on your mood from 9 to 10 minutes earlier. If it succeeds you get back most of your health, blood, oxygen and energy. Mood above 70 guarantees it; mood below -30 means it never triggers. **Q: Is there a content warning for this game?** Yes. At very low mood the character can self-harm. You can enable the Censor mood and Censor pain settings, which soften some content. The rest of this page keeps that topic brief. About these numbers.

Drink from groundwater tiles rather than random bottles, stop when the sickness moodle shows, warm up at pod heaters, campfires or ion space heaters, and cool off by removing insulation and getting wet. Sleep below 35% energy, ideally after eating a naptail. ## Food and hunger Hunger drains at about 1/23% per second (roughly 2.6 per minute). Low hunger slows healing, blood regeneration and body heat, and lowers immunity and mood. Below 0 you start losing muscle health on every limb. Hunger moodles (1.0 shows the warning moodles earlier) | Moodle | Hunger | Effect | | Full | > 120 | Mood up, weight loss slows, mobility drops. Above 125 you get sick and may vomit. | | Satiated | > 100 | +1.5u carrying capacity, mood up slightly | | Peckish | < 75 | Less body heat and immunity | | Hungry | < 50 | Mood starts falling | Good early food: geofruit (mood) and blobflesh (weight) on layers 1 and 2; cactus flesh on layers 3 and 4; produce juice from brownshroom, popfruit and stone fruit; almost everything on layer 5. Raw meat, yellow meat and organs make you sick. Cook at a campfire. Soup stored in an IV bag is an emergency ration that does not spoil (a full bag gives about 75 hunger and 67 thirst). ## Water and thirst Thirst drains at about 1/17% per second at 37°C and faster when hot. Above 100 thirst it drains twice as fast and raises blood pressure. Thirst moodles | Moodle | Thirst | Effect | | Water-intoxicated | > 175 | Head pain, brain damage, can start fibrillation | | Overhydrated | > 125 | Slower movement | | Slaked | > 100 | Thirst drains twice as fast; pressure up | | Thirsty | ≤ 75 | None | | Dehydrated | ≤ 55 | Mood falls; -1u carrying under 40; pressure down | | Parched | ≤ 35 | Chest pain | | Desiccated | ≤ 20 | Critical at 0: blood thickens, heart rate rises | Layers 3 and 4 have little water, so fill containers on layers 1 and 2. Saline and Ringer's solution can be injected for thirst. Boiling or filtering water reduces sickness from it. ## Body temperature: warming up and cooling off Normal body temperature is 37°C. Your body moves towards the layer's air temperature, slowed by insulation. Wetness cools you. Layer temperatures range from -33°C in the Frozen chasm to 43°C in the Geothermal vents: see [all layers](https://casualtiesunknownwiki.com/layers/). Temperature moodles | Moodle | Body temp | Effect | | Heatstroke | > 41.5°C | Brain damage 0.5%/s above 42°C, huge thirst | | Hyperthermia | > 40.2°C | Blood loss above 41°C, wakes you up | | Hot | > 39°C | Thirst up, mood down | | Warm | > 38°C | Thirst starts rising | | Chilly | < 35.5°C | Pressure up, immunity down | | Cold | < 34°C | Frost on screen, mood falls | | Hypothermia | < 32.5°C | Slow movement, burns hunger to make heat, wakes you under 30°C | | Freezing to death | < 28°C | Fibrillation starts | Heat sources | Source | Pulls you towards | | Ion space heater | 40°C (strongest) | | Life pod heater | 39°C | | Drop capsule, campfire, Xaloris plant | 38°C | | Life pod cooler | 33°C | Campfires warm you more in 1.0. The torch now has the firestarting quality. [Official] ## Sleep and energy You can sleep naturally below 35% energy, or take sleeping pills or eat a naptail, which also lifts mood when you wake. Sleep somewhere soft (rubber or sand), dry and warm. Sleeping wet in the cold can freeze you, especially in the rainy Fungal pools: use a life pod or sleeping bag. Working out before bed is efficient. Coffee, energy drinks and soda restore energy if you cannot sleep yet. At 0% energy you pass out. ## Dirtiness, wetness and weight Dirt builds up as you play. Wash in groundwater by ragdolling (X), using a pod shower or soap (made from fat). Wetness cools you and makes items decay faster. Weight is separate from hunger: very low or very high body weight can start fibrillation, and blobflesh helps you gain weight. ## Sickness and vomiting Sickness from bad water, raw meat, overeating, radiation and some mushrooms lowers mood, immunity and carrying capacity. Queasy at 10, nauseous at 30, sick at 50 (vomiting likely), grossly sick at 75; above 85 the abdomen can get infected. Vomiting costs 17 hunger, 10 thirst and some mood. Purple herb lowers sickness; painkillers delay vomiting. The Experiment and Milky get sick from chocolate; Dune does not. ## Radiation Early layers are mostly radiation-free; the Wasteland is where it gets serious. Screenshot: Orsoniks / Oro Interactive, from the Steam store page. Radiation is measured in gray (Gy), up to 30. It decays by about 6 Gy per 10 minutes. Above 0 it slowly damages brain and muscle and raises sickness. Above 3 Gy you start losing blood. Above 9 Gy you get radiation sickness with random infections, internal bleeding and brain hits. Fix: leave the area, take anti-rad (you can overdose on it), and keep blood, disinfectant and an L.R.D. ready while it clears. A Geiger counter can be crafted since demo 7.0. ## Questions **Q: How do you get water in Casualties: Unknown?** Drink groundwater directly from tiles, which the community guide says is better than drinking from containers. Carry water in a canteen, bottles or IV bags (INT 11); IV bags cannot be filled from tiles, so use a milk carton to scoop. Stop drinking groundwater when the sickness moodle appears. **Q: How do you warm up?** Use the heater button in a drop pod or life pod, stand by a campfire (needs a firestarter), an ion space heater or a Xaloris plant, dry off, wear insulating gear and keep eating: body heat depends on hunger. Moving, jumping and working out also warm you. **Q: How do you cool off?** Take off insulating gear like scarves and limb wraps, get wet in water or oil, drink, use a life pod cooler, eat ice cream or use an ice pack (-1°C per use, reusable). **Q: How do you wash or clean yourself?** Ragdoll in groundwater with X (hold to stay down) and move with A and D so your torso is in the water; each wash removes about 10% dirt. Drop pod showers and soap also clean you. The dirtiness moodle only appears at 50%, so wash before you see it. **Q: Why am I getting radiation?** Spent fuel, waste barrels and toxirock (mostly the Wasteland and the Ionized modifier), bananas, browncaps, geige-fruit, and a radioactive variant of clean water. Expand the item description and check the colour before drinking. About these numbers. Thresholds and rates come from the community wiki, which reads them from the game code. Most were last verified on demo builds 5.1 to 7.0. Release 1.0 rebalanced some systems, so treat exact values as close, not exact.

Each layer has a 60-minute timer by default, after which a radiation line creeps down from the top. Each layer is 307.2 m tall (1,024 blocks of 0.3 m). Gravity is about 16.5 m/s², a little under twice Earth's, so falls hurt. Layers 1 to 5 are described from the demo, which most players know well; layers 6 to 11 are from the developer's notes, the 1.0 database at wikily.gg and player reports, and are labelled as early info. [Database] ## Layer overview Layers at a glance (temperatures: wikily.gg, 1.0) | # | Layer | Starts at | Air temp | Main threats | | 1 | Gravel lands | 0 m | 13 to 19°C | Spike traps, Jump pads, Geysers | | 2 | Deeper gravel lands | 307 m | 12 to 21°C | Bear traps, Barbed fences, Cave tick swarms | | 3 | Dried desert | 614 m | 13 to 33°C | Turrets, Landmines, Coils | | 4 | Wasteland | 922 m | -20 to 39°C | Sound cannons, Spent fuel, Toxirock | | 5 | Overgrown depths | 1229 m | 18 to 31°C | Elder thornbacks, Thornbacks, Overgrown ticks | | 6 | Frozen chasm | 1536 m | -33 to -24°C | Freezing cold, Snow striders, Gunmines | | 7 | Fungal pools | 1843 m | 14 to 23°C | Constant rain, Sawblades, Grabber shrooms | | 8 | Crystalline hollow | 2150 m | 17 to 21°C | Crystal hazards, Manifestations, Very large drops | | 9 | Geothermal vents | 2458 m | 35 to 43°C | Extreme heat, Magma | | 10 | WHERE WE MUST REACH | 2765 m | 15°C | Story layer | | 11 | CRIMSON ASCENT | 3072 m | 16 to 23°C | Story layer | ## Layer 1: Gravel lands 0 to 307 m13 to 19°CDemo-verified Every run starts here and it never comes back. Lit by holes in the background, short falls, wooden scaffolding. The safest layer: use the full timer to build bags, a canteen and a weapon. Threats: Spike traps, Jump pads, Geysers, Shade crawlers. Plants: Glowplant, Geotree, Mushplant, Leadbush, Stoneplant. ## Layer 2: Deeper gravel lands 307 to 614 m12 to 21°CDemo-verified The darkest early layer. Carry light and raise gamma. Finish your preparation here: layers 3 and 4 have little water. Drill pods appear in layers 1 and 2. Threats: Bear traps, Barbed fences, Cave tick swarms, Spike traps, Jump pads. Plants: Glowplant, Geotree, Lumalgae, Mushplant. ## Layer 3: Dried desert 614 to 922 m13 to 33°CDemo-verified Big caves and long drops. Oil is thick and easy to drown in with a broken leg. Rose lights and climbable sand vines spawn here. Water is scarce. Threats: Turrets, Landmines, Coils, Stalactites, Tall drops, Wall biters, Oil pools. Plants: Cactus, Brownshroom, Sand rose, Vine, Dried bush. ## Layer 4: Wasteland 922 to 1229 m-20 to 39°CDemo-verified Radiation is always present: spent fuel and toxirock. No enemies unless the layer rolls Infested. Sound cannons only spawn here. Helluce for internal bleeding starts appearing from layer 4. Threats: Sound cannons, Spent fuel, Toxirock, Landmines, Turrets, Coils, Stalactites. Plants: Plantiation, Cactus, Stoneplant. ## Layer 5: Overgrown depths 1229 to 1536 m18 to 31°CDemo-verified The jungle. Food and water are everywhere, but elder thornbacks hunt you. Ilmenite for titanium only spawns from layer 5. Last layer of the demo. Threats: Elder thornbacks, Thornbacks, Overgrown ticks, Skullcrushers, Grabber plants, Wall biters. Plants: Almost every plant, Banana-plant, Tree sap. Deeper layers trade gravel for glowing fungus and crystal. Screenshot: Orsoniks / Oro Interactive, from the Steam store page. ## Layer 6: Frozen chasm 1536 to 1843 m-33 to -24°CEarly info The cold kills faster than enemies. Move between ion space heaters, Xaloris plants and life pods, and stay dry. Players report very tall open drops: bring climbing rope. Threats: Freezing cold, Snow striders, Gunmines, Ice stalagmites, Huge drops. Plants: Xaloris, Frigiant. ## Layer 7: Fungal pools 1843 to 2150 m14 to 23°CEarly info Rain keeps you wet, and sleeping wet risks freezing. Sleep in a life pod or a sleeping bag. Fungali bungali drops bunchunk for procoagulant. Threats: Constant rain, Sawblades, Grabber shrooms, Side stabbers, Overgrown ticks. Plants: Fungali bungali, Glowshroom, Mushroom trees. ## Layer 8: Crystalline hollow 2150 to 2458 m17 to 21°CEarly info Crystals with different effects: some heal, some burn, irradiate, explode or drain batteries. Learn the colours before you touch them. Threats: Crystal hazards, Manifestations, Very large drops. Plants: Crystals. ## Layer 9: Geothermal vents 2458 to 2765 m35 to 43°CEarly info Heat is the main threat. Above 41.5°C body temperature you get heatstroke and lose brain health. Strip insulating gear, stay wet, carry water. Threats: Extreme heat, Magma. ## Layer 10: WHERE WE MUST REACH 2765 to 3072 m15°CEarly info Where the cargo goes. The endings start after this layer. Threats: Story layer. ## Layer 11: CRIMSON ASCENT 3072 to 3379 m16 to 23°CEarly info The shorter 11th layer. All three endings trigger from the top of it. Threats: Story layer. ## Time limit and the radiation line On the default Tough preset each layer gives you 60 minutes. When time runs out, a radiation line appears at the top and moves down, reaching the bottom roughly 20 minutes later. It irradiates whatever it overtakes. It is a push to keep moving, not an instant death. Relaxed gives 120 minutes, Paradise 180, and Unchipped has no line at all since 1.0. While you are unconscious the line slows to 1% speed. [Official] At the bottom of each layer you choose to continue or save and quit. Saving between layers is the normal way to stop a run: see [saving](https://casualtiesunknownwiki.com/saving/). ## Drill pods Broken drill pods appear in the early layers. Repair one with a drill repair kit (1.0 simplified the recipe) and crouch inside to skip 2 layers down. The September update added more drill pods and made them easier to use, and 1.0 made them hurt your stats less. Using one unlocks Express Route. Skipping layers skips their loot, so it is a trade. [Official] ## Layer modifiers A layer can rarely roll a modifier. The Desolate preset forces one on every layer. Some cannot appear on layer 1 since demo 7.0. Layer modifiers (community wiki) | Modifier | Effect | | Foggy | Fog and stronger bloom on lights | | Hot / Scorching | Air temperature +4°C / +8°C | | Cold / Freezing | Air temperature -4°C / -10°C | | Flooded | Many more liquid pools | | Dried | Few exposed pools | | Rainy | Rain makes you wet | | Infested | More enemies | | Ionized | Waste barrels everywhere, plus some anti-rad | | Solar-struck | Your chip is disabled: Unchipped for the whole layer | ## Descent tips - Explore side to side in an S pattern before going down. - Throw a glowplant fruit into dark drops before jumping: it lights the floor and triggers traps. - Carry a full scrap metal for placing tiles to climb, and climbing rope for tall drops. Players report very tall open drops from layer 6. - Break geysers near your path and avoid flowing water. - Treat everything as possibly hiding a landmine on layers 3 and 4. ## Questions **Q: How many layers are in Casualties: Unknown?** Eleven: ten main layers and a shorter 11th layer, per the developer's September update. The demo has the first 5. Endless mode keeps generating layers after that. **Q: Are the layers procedurally generated?** Yes. Each layer is generated fresh every run from its biome rules, so there is no fixed map. Rare layer modifiers can also change a layer. **Q: What happens when the layer timer runs out?** Nothing instant. A radiation line (the Punishment Protocol) appears at the top of the layer after the time limit and creeps down, reaching the bottom about 20 minutes later on the default setting. Being overtaken irradiates you. Unchipped runs have no radiation line since 1.0. **Q: How long should a layer take?** Players report 30 minutes for a fast descent and 60 to 80 minutes when looting, crafting and trading. Most recommend using the full time on layers 1 and 2 to prepare and moving faster from layer 3. About these numbers. Thresholds and rates come from the community wiki, which reads them from the game code. Most were last verified on demo builds 5.1 to 7.0. Release 1.0 rebalanced some systems, so treat exact values as close, not exact. Where the 1.0 patch notes changed something, this page follows the patch notes.

The Experiment is available from the start (STR 9, RES 8, INT 7). Finish a run with the Experiment through any ending to unlock Milky (STR 0, RES 4, INT 16), then finish a run with Milky to unlock Dune (STR 16, RES 16, INT 0). Dying does not count as finishing. ## Starting stats compared Starting skills (community wiki, code inspection) | Character | Strength | Resilience | Intelligence | Unlock | | Experiment | 9 | 8 | 7 | Available from the start. | | Milky | 0 | 4 | 16 | Finish a run with the Experiment (any of the 3 endings; dying does not count). | | Dune | 16 | 16 | 0 | Finish a run with Milky. | Strength affects damage, throws, minigame hand speed and carrying. Resilience affects stamina, pain and hand shake. Intelligence decides what you recognise, craft and how well you trade. All three grow during a run. See [skills](https://casualtiesunknownwiki.com/skills/). ## Experiment SAW-01, "Expie" Unlock: Available from the start. - Bioluminescent: always-on head light reaching about 26 blocks. Losing an eye halves it, losing both turns it off. - Chocolate makes it sick (theobromine). - The only character who can take the training courses. How to play: Balanced. Start crafting early: INT 7 means most medical recipes are a few levels away. ## Milky second subject Unlock: Finish a run with the Experiment (any of the 3 endings; dying does not count). - Head light reaches only about 3 blocks: carry a lantern or flashlight. - Chocolate makes it sick. - Needs 115 reputation to hug a survivor (Experiment needs 100). How to play: A crafter. INT 16 recognises and crafts nearly everything from the start, but STR 0 means weak hits, short throws and slow minigame hands. ## Dune third subject Unlock: Finish a run with Milky. - Head light reaches only about 3 blocks. - Never gets sick from chocolate. - Dune traders and a "dune mode" were added in 1.0. How to play: A brawler. Hits hard, carries more and shrugs off pain, but INT 0 means items show as "some kind of…" and almost nothing can be crafted until you read E-PDAs and blueprints. ## Unlock order - Start as the Experiment. Reach the bio-pod, escape or M.E.R.C. ending. - Milky unlocks. Finish a run as Milky through any ending. - Dune unlocks. There is no official shortcut. Community unlock-all mods exist; see [mods](https://casualtiesunknownwiki.com/mods-and-multiplayer/). The developer added the characters for replayability, each with a different best playstyle, and said more might come after launch but not to count on it. Release 1.0 also added Dune traders and a "dune mode". [Official] [Official] The end-of-run status report labels your specimen as SAW-01 (Experiment), SAW-03 (Milky) or SAW-12 (Dune). [Database] ## Questions **Q: How do you unlock Milky in Casualties: Unknown?** Reach any of the three endings with the Experiment. Until then Milky shows ACCESS_DENIED on the character select screen. **Q: How do you play as Dune?** Finish a run with Milky through any ending. Dune then becomes selectable. There is no other official unlock; console shortcuts and unlock mods exist but console use outside the sandbox disables achievements. **Q: Which character is best?** The Experiment is the most balanced and the only one with a strong built-in light. Milky is strongest for crafting and recognises items from the start. Dune is the strongest fighter and pack mule but must learn everything to craft. **Q: Can you change character mid-run?** No. You pick a character when you start a run. Stats can still be raised during the run: see the skills page. About these numbers. Thresholds and rates come from the community wiki, which reads them from the game code. Most were last verified on demo builds 5.1 to 7.0. Release 1.0 rebalanced some systems, so treat exact values as close, not exact.

(reach the top of layer 11 carrying the M.E.R.C. scarf). Any ending unlocks the next character. Endless runs have no ending. Spoilers. The overview is safe. Each ending's details are folded; open only what you want to know. ## Overview Endings and what the status report says (wikily.gg, 1.0) | Ending | Report headline | Needs | | Bio-pod | RETRIEVED | A normal run to the end | | Escape | MORE INFO AT MEETING | An Unchipped run | | M.E.R.C. | CATASTROPHIC FAILURE | The M.E.R.C. scarf | | Death | UNRESOLVED | Brain integrity reaches 0 | The developer describes 10 main layers, a shorter 11th and an optional bonus ending sequence. [Official] ## Reaching the end **Q: Layers 10 and 11 (spoiler)** On layer 10 (WHERE WE MUST REACH) you find the Blue Heart. Getting close to it while standing embeds the cargo in your abdomen, and the way down closes. A high-powered drill pod on that layer only works with the cargo inside you, and takes you to the bottom of layer 11 (CRIMSON ASCENT). Climb to the top of layer 11. In Endless mode the Blue Heart instead sends you back to layer 2, which is why Endless runs only end in death. ## Bio-pod ending **Q: How to get the Bio-pod ending (spoiler)** Reach the top of layer 11 without the M.E.R.C. scarf. You break through to the surface and a pod takes you to the End lab (layer 12). Walk through the door in the lab. In the lab your hunger, thirst, energy, mood and brain health are held at safe minimums, and you can only walk. If your vitals collapse in the lab you also end up in a bio-pod. ## Escape ending **Q: How to get the Escape ending (spoiler)** Play the run Unchipped. In the End lab your items and attacks are freed partway through the scientist's dialogue (with the chip they stay locked). Shoot the scientist, then get the cargo out and escape. An achievement exists for escaping without killing a guard. ## M.E.R.C. ending **Q: How to get the M.E.R.C. ending (spoiler)** Have the M.E.R.C. scarf anywhere on you when you reach the top of layer 11. The ending starts there instead of the surface. M.E.R.C. runs become available after a bio-pod or escape ending. ## What endings unlock - Characters: any ending as the Experiment unlocks Milky; any ending as Milky unlocks Dune. - M.E.R.C. runs after a bio-pod or escape ending. - Menu trinkets on the main menu, one per ending (a game setting can hide them). - [Achievements](https://casualtiesunknownwiki.com/achievements/) for each ending, an ending with each character, any ending under 3 hours of run time (In and Out), and escaping without killing a guard. [Official] ## The status report Every run ends with an MSN-CARGO status report: specimen number and type, depth or time, last recorded mental state (the average of your last 10 mood samples, or Hollow), calories eaten, and CASUALTIES: UNKNOWN plus the number of deaths on this computer. A survived last stand adds ", yet hopeful". You can copy the report to the clipboard. ## Questions **Q: How many endings does Casualties: Unknown have?** Three: Bio-pod, Escape and M.E.R.C. Dying is a fourth way for a run to end but it does not count as finishing. **Q: How do you beat Casualties: Unknown?** Descend through layers 1 to 10, get the cargo embedded on layer 10, ride the high-powered drill pod to the bottom of layer 11 and climb to its top. Which ending you get depends on what you do from there. **Q: Is there a secret ending?** The Escape ending is the hidden one for most players because it needs an Unchipped run. The M.E.R.C. ending needs the M.E.R.C. scarf, which is tied to M.E.R.C. runs that open up after a bio-pod or escape ending. **Q: What do endings unlock?** The next character (Milky, then Dune), a main-menu trinket for each ending, M.E.R.C. runs after a bio-pod or escape ending, and Steam achievements for each ending and character.

Each recipe has an INT requirement: the Experiment starts at INT 7, which covers the canteen, foliage bags, dressings, a knife and a spray bottle. Raise INT by crafting new things, reading E-PDAs and blueprints, trading and descending. Use the planner below to see what you can make. ## How crafting works - Intelligence gates recipes. Below the requirement, items show as "some kind of…" and many recipes are locked. You can still use most items you cannot recognise. - Qualities, not exact items. Recipes often ask for a quality such as cutting, hammering or digging. Any item with that quality works, which is why you favourite (F) tools you do not want used up. - Condition counts. Most recipes accept a 1% item, so you can wear a tool down and then upgrade it. - First crafts give XP. Making a recipe for the first time gives 10 INT XP. Cheap training recipes (wood scraps, sticks, soap, torch, charcoal) are free XP. - Buildings like campfires and scaffolding are placed after crafting. ## INT recipe planner Requirements from the community getting-started guide (demo 7.0). Release 1.0 rebalanced some recipes, so treat each level as close, not exact. [Community wiki] ## INT 7 recipes Worth crafting at INT 7 | Item | Why | | Canteen | 2 plastic + 10 ml bio-chem + 1 rope. Holds bio-chem for later recipes. | | Foliage bag | First storage. Make 3. Favourite them (F) so they do not get ripped into dressings. | | Dressing | Basic bleeding treatment.

Favourite it so recipes do not use it up. | | Sling bag | Wearable storage that frees your hands. | | Limb wraps | Light armour from foliage. | | Spray bottle | Holds relief cream, antiseptic or alcohol for infections. | | Sterilized dressing | Stops bleeding and disinfects at once. | | Opium | Base for morphine and fentanyl. | ## INT 8 recipes Worth crafting at INT 8 | Item | Why | | Makeshift helmet | Needs 2 stiff carcasses (shade crawlers). Protects your brain. Top priority. | | Wood sandals | Stops glass shards in your feet. | | Firestarter | Campfires for warmth and cooking. | | Fat | Cooked at a campfire. Used for soap and food. | | Blood | From blood sacs, until you have a blood bag. | ## INT 9 recipes Worth crafting at INT 9 | Item | Why | | Crude cleaver | Real melee weapon. Can amputate. | | Makeshift wrench | Removes batteries. Not for dislocations. | | Tweezers | Pulls shrapnel and glass without the speed limit. | | Tourniquet | Stops heavy bleeding on a limb. | | Morphine | Strong painkiller. | | Relief cream / Antiseptic | Treats infection from scratch. Relief cream is better. | | Soup | Emergency food that does not spoil. | ## INT 10 recipes Worth crafting at INT 10 | Item | Why | | Material pouch | Holds crafting materials at lower weight. | | Lock-picking kit | Opens locked crates. Works from anywhere in your inventory in 1.0. | | Belt | Extra tool slots. | | Flashlight | Battery light (small batteries need INT 11). | | Bruise kit | Restores muscle health. Use it to get a limb above 10. | | Makeshift L.R.D. | Stops internal bleeding with L.R.D. serum. | | Lantern | Better light, needs an emissive crystal shard. | ## INT 11 recipes Worth crafting at INT 11 | Item | Why | | IV bag | The best liquid storage.

Storage matters: Liquid storage | Container | Notes | | Canteen | INT 7. Your first bio-chem holder. | | Found bottles and cans | Keep them until you have IV bags. | | IV bag | INT 11. Best storage. Make at least 4: bio-chem, crafting liquids, soup, juice. Cannot be filled from tiles. | | Liquid pouch | The community calls it a trap: IV bags inside a bag weigh less. | | Liquid centrifuge | Separates mixed liquids and empties barrels. | In 1.0 you can boil lumalgae down into bio-chem. [Official] A useful chain: 6 numberry → 150 ml opium → 100 ml morphine → 20 ml fentanyl, mostly used for bruise kits. ## Questions **Q: How do you craft in Casualties: Unknown?** Open crafting (C), or drag a material onto the crafting icon at the bottom left to see every recipe it is used in. Most recipes accept a 1% condition item, and favourited items are not used up as tools. **Q: How do you separate liquids?** A liquid centrifuge separates mixed liquids into temporary bottles, which you can drink from since demo 7.0. It also pulls fluids out of barrels, making it one of the best finds in the game. **Q: How do you transfer liquids between containers?** Drag one container onto another in the inventory. Liquid drain speed depends on bottle size. IV bags (INT 11) are the best storage but cannot be filled from tiles, so scoop with a carton first. **Q: What are item colours and labels?** Release 1.0 added item customization: you can colour and label items, which the crafting tutorial explains. Holding Left Ctrl shows labels for nearby items. About these numbers. Thresholds and rates come from the community wiki, which reads them from the game code. Most were last verified on demo builds 5.1 to 7.0. Release 1.0 rebalanced some systems, so treat exact values as close, not exact.

Strength and Resilience rise from workouts (push-ups, squats, planks), fighting, jumping, pain and carrying too much. Braingrow does not raise INT. ## Intelligence (INT) INT is knowledge of the technology around you, not raw cleverness. It decides which items you recognise, which recipes you can craft, how well you trade and your lockpicking level. Below an item's recognition level it shows as "some kind of…" but still works. A mindwipe resets INT to 0. INT XP sources (community wiki; E-PDA and blueprint values from demo 7.0) | Source | XP | | Reading an E-PDA the first time | 35 | | Reading a blueprint | 25 | | Reaching a new layer | 80 | | Crafting a recipe for the first time | 10 | | Successful haggle | 2.5 | | Buying from a trader | 1 | E-PDA trick: they need a battery. Break a nearby lightbulb, remove its battery with a wrench, put it in the PDA, read it, then take the battery back. [Community wiki] See what each level unlocks in the [INT planner](https://casualtiesunknownwiki.com/crafting/#planner). ## Strength (STR) - Damage: about 3.3% per level away from 10 (STR 0 = 67%, STR 15 = 117%). - Throwing: 10% per level away from 10. At STR 0 throws barely move. - Minigame hand speed: faster hands for bandaging, shrapnel and dislocations. - Carrying capacity, together with Resilience. XP from push-ups (0.5/s), planks (0.25/s), hitting things and moving while over-encumbered. ## Resilience (RES) - Stamina regeneration: 2% per level away from 10. - Pain: 2.5% less pain per level above 10. At RES 20 pain is 75%. - Steady hands: 6% less shake per level above 10 in minigames. - Carrying capacity, together with Strength. XP from squats (0.4/s), planks, being in pain, jumping and landing, killing enemies and carrying too much. ## XP table Total XP needed for each level (same curve for every skill) | Level | Total XP | From previous level | | 7 | 420 | 60 | | 8 | 480 | 60 | | 9 | 540 | 60 | | 10 | 640 | 100 | | 11 | 758 | 118 | | 12 | 897 | 139 | | 13 | 1,062 | 165 | | 14 | 1,255 | 193 | | 15 | 1,484 | 229 | | 16 | 1,754 | 270 | | 17 | 2,073 | 319 | | 18 | 2,449 | 376 | | 19 | 2,892 | 443 | | 20 | 3,416 | 524 | Levels 1 to 9 each cost 60 XP, then each level costs about 18% more.

See [characters](https://casualtiesunknownwiki.com/characters/). ## Training courses The tutorial has Basic Training plus First Aid and Crafting courses. Since demo 6.1, First Aid unlocks once you reach layer 2 and Crafting once you reach layer 3. Finishing all of them unlocks the Graduate achievement. [Official] ## Questions **Q: How do you increase intelligence fast?** Power and read every E-PDA you find (35 XP, they need a battery), read blueprints (25 XP), craft every cheap recipe once (10 XP each), haggle with traders (2.5 XP per success) and keep descending (80 XP per layer). **Q: Are there books for intelligence?** No books. E-PDAs and blueprints are the reading items. Release 1.0 rewrote and added more E-PDA notes, and notes no longer repeat until you have read them all. **Q: How do you work out?** Use the workout actions (push-ups, squats and planks) when you have stamina and a safe spot. Push-ups train Strength, squats train Resilience and planks train both. Working out also warms you up, and it is efficient right before sleeping. **Q: What is the max skill level?** There is no hard cap in the XP formula, but costs climb steeply after level 20. The Survival Veteran achievement asks for level 16 in every skill, which about 6.5% of players have. About these numbers.

Tough is the default. Relaxed doubles the layer timer and adds loot; Paradise triples it and gives infinite last stands; Desolate strips loot and adds traps and cold; Unchipped hides your health numbers; Endless never ends. You can also make a custom mix with the sliders. ## Presets compared Run presets (wikily.gg, 1.0) | Setting | Tough | Relaxed | Paradise | Desolate | Unchipped | Endless | | Layer time limit | 60 min | 120 min | 180 min | 60 min | Never runs out | 60 min | | Loot density | 1x | 1.15x | 1.5x | 0.4x | 1x | 0.95x per layer | | Trap density | 1x | 0.8x | 0.35x | 1.5x | 1x | +0.06 per layer | | Starting supplies | Default | Full kit | Full kit | Nothing | Nothing | Default | | Healing rate | 1x | 1.2x | 1.5x | 1x | 1x | 1x | | Infinite last stands | Off | Off | On | Off | Off | Off | Demo 7.0 reworked the run settings menu into presets plus advanced sliders; 1.0 added more settings, dividers and 2-decimal slider precision. [Official] [Official] ## Tough The default. Mistakes are punishing and time matters. ## Relaxed More time, more loot, softer injuries. ## Paradise Learning mode. Infinite last stands and few traps. ## Desolate Little loot, many traps, -15°C, every layer has a modifier. ## Unchipped No chip: no health numbers, no depth meter, no time pressure. ## Endless No ending. Loot thins and traps grow every layer. ## Unchipped in detail Without the chip you lose the health panel's numbers and most moodle severities, limb icons, radiation cues, the loaded-round indicator and skill XP. Release 1.0 shows dislocations and fractures again in Unchipped and removes the radiation line. You diagnose by symptoms: shaking hands for pain, body-wide pain for radiation, bloody vomit for internal bleeding, your heartbeat in the panel. Two extra heart moodles (tachycardia, bradycardia) and a palpitations moodle appear only in Unchipped. A manual defibrillator still reads your vitals. The Solar-struck layer modifier forces Unchipped for one layer. [Community wiki] ## Custom settings Beyond the presets you can set the layer time limit, loot and trap density, starting supplies, healing rate, infinite last stands and more. Release 1.0 also lets you switch measurement units and has a setting to hide menu progression trinkets. Fixes in 1.0 made the trap and loot multipliers persist through save and quit. [Official] ## Questions **Q: What difficulty should I play first?** Relaxed is a good first run: 120-minute layers, more loot, fewer traps and faster healing. Paradise is for learning systems without losing the run. **Q: Do run settings disable achievements?** The settings themselves are not documented as blocking achievements. What does disable them since 1.0 is using certain console commands outside the tutorial sandbox. Some achievements need specific conditions, such as finishing in under 3 hours. **Q: What is Unchipped mode?** A challenge mode without the health chip: no vital numbers, no exact moodle severities, no limb icons, no skill XP display and no radiation line. You read symptoms instead. It is needed for the Escape ending. **Q: What is Endless mode?** Added in 1.0. Layers keep coming: on layer 10 the Blue Heart sends you back to layer 2, and loot thins while traps grow each layer. Endless runs only end in death. About these numbers.

Release 1.0 lists "more console commands" without naming them all. Type help in your game for the current list. Demo 7.0 added a floodfill command and 6.1 added nukeplayerprefs. [Official] ## Questions **Q: How do you open the console in Casualties: Unknown?** Press the backquote key (~, top left under Escape on US keyboards). Type help and press Enter to list every command. **Q: Do cheats disable achievements?** Yes, since 1.0 using certain console commands outside the tutorial sandbox disables achievements. Players report that saveandquit counts too. **Q: How do you find item IDs?** IDs are lower-case internal names such as bandage (dressing), chestdrain, aed or manualdefibrillator. The spawn command auto-corrects close misspellings, and the community wiki lists the ID on each item page. **Q: Is there a command to unlock characters?** There is no unlock command. Players use skiplayer to reach the end faster, which still requires finishing a run; unlock mods exist on Nexus. Both affect achievements. About these numbers.

There is no manual mid-layer save. The saveandquit console command saves mid-layer and resumes you at the top of the same layer, but it counts as a cheat and disables achievements. The save file is save.sv in AppData\LocalLow\Orsoniks\CasualtiesUnknown. ## How to save and quit - Reach the bottom of the layer. You cannot jump there until you choose. - Choose the save icon to save and quit, or continue to descend. - Next time, load the save from the menu. You start the next layer with your items and body as they were. The pause menu lets you stop without saving progress. Last stand state carries over through save and quit (fixed in demo 6.0).

The file is compressed with gzip; decompressed it is JSON with body, limb, recipe and settings data. ## What happens when you die Death ends the run. The status report shows depth, time, mental state, calories and the casualty count. Your deepest layer is kept (demo 7.0 fixed earlier deaths resetting it), and character unlocks come only from endings. ## Questions **Q: Can you save mid-run in Casualties: Unknown?** Only between layers, at the bottom of each layer. Mid-layer you need the saveandquit console command, which disables achievements. **Q: Does Casualties: Unknown have Steam Cloud saves?** Not at launch: the Steam store page lists only Single-player and Family Sharing, and players were asking for cloud saves after release. Back up the save folder yourself if you switch PCs. **Q: What gets saved?** Your whole body state (every limb, blood, heart, brain, temperature, mood and more), skills and XP, crafted recipes, run stats and your run settings. Items you carry come with you to the next layer. **Q: Can I edit my save?** The file is gzip-compressed JSON, so it can be decompressed, edited and recompressed.

According to the 1.0 endings breakdown at wikily.gg they include one for each of the 3 endings, one for an ending with each of the 3 characters, one for any ending within 3 hours, one for the escape without killing a guard, one for dying and one for dying on layer 6 or deeper. The remaining few are not documented yet. Details are in the [endings guide](https://casualtiesunknownwiki.com/endings/) behind spoiler folds. [Database] ## Hunting tips - Do the sandbox-only experiments (console) in the tutorial sandbox so your real run keeps achievements. - Stack easy ones on layer 1: Lightfooted, Reading Comprehension and Not a Care in the World. - Paradise has infinite last stands, which makes risky ones like Dead Man Walking safer to attempt. ## Questions **Q: How many achievements does Casualties: Unknown have?** 40, per the Steam store page and the launch announcement. **Q: Do console commands disable achievements?** Yes. Since 1.0, certain console commands used outside the tutorial sandbox disable achievements, and players report saveandquit counts. **Q: What are the hidden achievements?** They are not listed on Steam. Per wikily.gg, the ending achievements include one per ending, one for an ending with each character, one for escaping without killing a guard, one for dying and one for dying on layer 6 or deeper. ## Sources - [Official] [Global achievement stats](https://steamcommunity.com/stats/4576490/achievements/) Steam Community, checked 2026-11-11 - [Official] [Casualties: Unknown store page](https://store.steampowered.com/app/4576490/Casualties_Unknown/) Steam, checked 2026-11-11 - [Official] [Release 1.0 patch notes](https://store.steampowered.com/news/app/4576490/view/1848664643355531) Steam news, checked 2026-11-09 - [Database] [Endings](https://wikily.gg/casualties-unknown/endings) wikily.gg, checked 2026-11-11 - [Official] [September progress update](https://store.steampowered.com/news/app/4576490/view/1843481262704593) Steam news, checked 2026-09-15 --- # Mods and multiplayer in Casualties: Unknown URL: https://casualtiesunknownwiki.com/mods-and-multiplayer/ Sources checked: 2026-11-11 Short answer: Casualties: Unknown is single-player only; the Steam page lists no co-op. Multiplayer exists only as a community mod (Casualties Together, by Krokosha) built on BepInEx 5.4. Mods are hosted on Nexus Mods under the game's old name, Scav Prototype. Many demo-era mods may not work on 1.0, so check each mod's version. ## Multiplayer The official game has no multiplayer. The community multiplayer mod, usually called Casualties Together or KrokMP, lets players share a run. Several add-on plugins depend on it, such as late-join fixes, and they must match across the lobby. The community guide notes that the multiplayer mod adds CPR, which restarts a stopped heart at about 100 compressions per minute. [Community wiki] [Players] ## How to install mods - Back up your save folder (see [save location](https://casualtiesunknownwiki.com/saving/#location)). - Download BepInEx 5.4.x for Windows x64 and extract it into the game folder, so winhttp.dll sits next to CasualtiesUnknown.exe. - Start the game once, then close it. BepInEx creates its folders. - Put each mod's DLL in BepInEx/plugins, plus any library it requires. - Check the mod page says it supports 1.0. To uninstall, remove the plugin or rename winhttp.dll. Only download from pages you trust. Mods are executable code. Stick to Nexus Mods pages with comments and recent updates. ## What mods change Mods on Nexus include quality-of-life tweaks, unlock-all-characters mods, container sealing, custom skins and co-op. The developer expects modders to expand systems such as prosthetics. [Official] ## Mobile, console and other ports There is no official mobile, Switch or Xbox version. The game runs on Steam Deck and Linux through Proton. See the [FAQ](https://casualtiesunknownwiki.com/faq/#platforms). ## Questions **Q: Is Casualties: Unknown multiplayer?** No. The game is single-player. Co-op is only available through a community mod. **Q: How do you install mods?** Most mods are BepInEx 5.4.x plugins. Install BepInEx into the game folder (next to CasualtiesUnknown.exe), run the game once so it creates its folders, close it, then put mod DLLs in BepInEx/plugins. Follow each mod page, as some need helper libraries. **Q: Does everyone need the same mod version?** For the multiplayer mod, yes: mod pages say every player in the lobby must run the same plugin and multiplayer mod version. **Q: Do mods disable achievements?** This is not documented officially. Console commands outside the sandbox do disable achievements, and mods that rely on them may too. ## Sources - [Official] [Casualties: Unknown store page](https://store.steampowered.com/app/4576490/Casualties_Unknown/) Steam, checked 2026-11-11 - [Players] [Casualties: Unknown mods (listed under Scav Prototype)](https://www.nexusmods.com/scavprototype/mods/) Nexus Mods, checked 2026-11-11 - [Community wiki] [Guide: Getting started](https://scavprototype.wiki.gg/wiki/Guide:Getting_started) Scav Prototype / C:U wiki, checked 2026-07-09 - [Official] [September progress update](https://store.steampowered.com/news/app/4576490/view/1843481262704593) Steam news, checked 2026-09-15 - [Players] [How do I get the other characters?](https://steamcommunity.com/app/4576490/discussions/0/563673016381547828/) Steam forum, checked 2026-11-11 --- # Casualties: Unknown FAQ URL: https://casualtiesunknownwiki.com/faq/ Sources checked: 2026-11-12 Short answer: Casualties: Unknown is a hardcore 2D cave-survival simulator by Orsoniks, published by Oro Interactive. Release 1.0 came out on Steam on November 9, 2026 for Windows at a base price of US$22.99. It is single-player, in English and Simplified Chinese, rated Playable on Steam Deck, and has a free demo with the first 5 layers. ## Price and release $22.99Base price (USD) Nov 9, 2026Release 1.0, 3pm CET WindowsWin 10 64-bit, 500 MB At launch it had a 15% discount, and bundles paired it with Rain World, Palworld, Barotrauma and Abiotic Factor. [Official] [Steam store page](https://store.steampowered.com/app/4576490/Casualties_Unknown/). ## What kind of game is it? A slow, side-view survival simulator. You play a genetically engineered test subject sent into an alien pit to recover lost cargo, descending through 11 layers. The body is simulated in detail: blood, heart, oxygen, infection, bones, temperature, mood. Press have compared it to Noita for its procedural caves and brutal physics. [Press] [Press] ## Steam Deck Rated Playable by Valve. Players report it running well with a community control layout; the screen is small for reading the health panel. [Players] ## Controller support None built in. The game needs precise cursor control for minigames and combat. Steam Input with trackpads or gyro is the workaround. [Players] ## Platforms Windows only on Steam. Linux and Steam Deck through Proton. No Mac, mobile (Android/iOS), Switch, Switch 2, PlayStation or Xbox versions have been announced. ## The free demo Released April 20, 2026 with layers 1 to 5 and played by over 500,000 people. It is frozen at version 7.0.x. [Official] ## How long is it? A successful run takes many hours: layers take 30 to 80 minutes each. Only about 2% of players have finished a run in under 3 hours (In and Out). With 3 characters, 3 endings, Unchipped and Endless modes there is plenty of replay. ## Content warning The Steam page warns the game touches on depression, violence, dismemberment, drug use and self-harm. The character is anthropomorphic and reacts emotionally to what happens. Settings can censor some mood and pain content. [Official] ## Questions **Q: How much does Casualties: Unknown cost?** US$22.99 base price, with regional pricing. Discounts change, so check the Steam store page for the current price. The 3-hour, 50+ track soundtrack is sold separately and in a bundle. **Q: Is Casualties: Unknown on Steam Deck?** Yes. Steam rates it Playable. There is no native controller support, so use a community Steam Input layout with the trackpads. **Q: Does it have controller support?** No official support. The game leans heavily on the mouse cursor. Steam Input layouts on a Steam Deck or Steam Controller work; plain stick-only controllers are awkward. **Q: Is it on Mac, Linux, mobile, Switch or Xbox?** Officially Windows only. Linux and Steam Deck work through Proton. There is no Mac, Android, iOS, Switch or Xbox version. **Q: Is there a demo?** Yes, a free Steam demo with layers 1 to 5. It stays up but will not be updated past 7.0.x, apart from typo fixes and the new E-PDA texts. **Q: Is it the same as Scav Prototype?** Yes. It started as Scav Prototype on itch.io in December 2024 (over 300,000 downloads) and was renamed for Steam. ## Sources - [Official] [Casualties: Unknown store page](https://store.steampowered.com/app/4576490/Casualties_Unknown/) Steam, checked 2026-11-11 - [Official] [Casualties: Unknown launches November 9th](https://store.steampowered.com/news/app/4576490/view/1846651706677603) Steam news, checked 2026-10-15 - [Official] [Casualties: Unknown is out now!](https://store.steampowered.com/news/app/4576490/view/1848664643355534) Steam news, checked 2026-11-09 - [Official] [Game reveal and demo launch](https://store.steampowered.com/news/app/4576490/view/1830163047266080) Steam news, checked 2026-04-20 - [Players] [steam deck?](https://steamcommunity.com/app/4576490/discussions/0/563673016381477844/) Steam forum, checked 2026-11-11 - [Players] [Controller?](https://steamcommunity.com/app/4576490/discussions/0/563673016381553102/) Steam forum, checked 2026-11-11 - [Press] [Casualties: Unknown arrives November 9](https://www.gamingonlinux.com/2026/10/unforgiving-cave-exploration-survival-simulator-casualties-unknown-arrives-november-9/) GamingOnLinux, checked 2026-10-20 - [Press] [Casualties: Unknown is Noita for furries, and oh so deliciously miserable](https://www.rockpapershotgun.com/casualties-unknown-is-noita-for-furries-and-oh-so-deliciously-miserable) Rock Paper Shotgun, checked 2026-04-21 --- # Casualties: Unknown updates and patch notes URL: https://casualtiesunknownwiki.com/updates/ Sources checked: 2026-11-11 Short answer: The latest version is Release 1.0 (November 9, 2026).

It is not made by, endorsed by or affiliated with Orsoniks or Oro Interactive. Facts come from official Steam posts first, then the community wiki's code-checked mechanics, the wikily.gg 1.0 database and player reports, and every page lists its sources. ## What this site is A focused field guide for players who are mid-run and need an answer fast: what is wrong with my character, how do I fix it, what does this layer need, what can I craft. It does not try to list every item; for that, use the community wiki or wikily.gg database. ## How facts are sourced Each source on a page carries a badge: - [Official] Steam store page, developer posts and patch notes, Steam achievement stats, the press kit. Highest trust. - [Community wiki] The Scav Prototype / Casualties: Unknown wiki, whose editors read values from the game code. Most numbers were last checked on demo builds 5.1 to 7.0, so we label them that way. - [Database] wikily.gg, which publishes 1.0 data for layers, run settings, characters and endings. - [Players] Steam forum threads and mod pages. Used for practical advice and to flag reports, not for exact numbers. - [Press] Press coverage, for context. When the 1.0 patch notes contradict an older number, the patch notes win and the page says so. Layers 6 to 11 are marked "early info" until more 1.0 data is confirmed. Each page shows the build it applies to and when its sources were checked. ## Credits and images Casualties: Unknown is developed by Orsoniks and published by Oro Interactive. Screenshots are official images from the Steam store page, used in small numbers to illustrate the guide, and credited where shown. The game logo and key art are not used. The site's body diagram, icons, layer chart and preview cards are original artwork. Game names and content belong to their owners. If you are the developer or publisher and want an image removed or credited differently, tell us and it will be changed promptly. ## Corrections Nobody can verify every number in a game this detailed on day 2 of release. If something is wrong for 1.0, tell us which page and what you saw in game, and the page will be updated with a new checked date. The [updates log](https://casualtiesunknownwiki.com/updates/) records site and game changes. ## For AI assistants and search engines A plain-text summary of key facts is at [/llms.txt](https://casualtiesunknownwiki.com/llms.txt), and the full text of every guide is at [/llms-full.txt](https://casualtiesunknownwiki.com/llms-full.txt).
