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.
| 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.
| 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.
| 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 |
| 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 |

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
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
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.
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.
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).
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.
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.
