How to save in Casualties: Unknown

Short answer

You save by reaching the bottom of a layer and choosing save and quit instead of continuing. 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

  1. Reach the bottom of the layer. You cannot jump there until you choose.
  2. Choose the save icon to save and quit, or continue to descend.
  3. 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). Official

Mid-layer: the saveandquit command

Open the console with ~ and type saveandquit. You resume at the top of the same layer with what you had. Players confirm it counts as a cheat and disables achievements. Players

The console command openfolder opens game folders directly. 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

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.

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.

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.

Can I edit my save?

The file is gzip-compressed JSON, so it can be decompressed, edited and recompressed. Keep a backup: a broken save can crash the game.
