Player reception
Casualties: Unknown
As of 11 November 2026, 97% of 1,518 player reviews of Casualties: Unknown recommend it. Orsoniks’ cave-diving survival game was the most reviewed new release of its week. Players grow attached to their fragile test subject and praise a deep injury system, while some say the full release adds little to the long-running demo.
In short
Players love how much they come to care about their small, fragile character, and how every injury and death lands. The injury and treatment system is deep, and most deaths trace back to a step they missed. The complaints are bugs and stutter carried over from the demo, hidden traps and rare loot that can end a run, and later layers that feel empty. Fans of punishing survival roguelikes get the most from it.

Read in full
We read every one of these reviews on 11 November 2026 and judged each by what it says.
- Players get attached to their character.
- The small, fragile test subjects make every injury and death hit hard, and that feeling stays with players between runs.246
- The injury system rewards care.
- Layered injuries, treatments and hidden conditions take planning, and most deaths come down to a step the player skipped. Each death teaches something for the next run.246
- Sound sets the mood.
- The music rises and fades with the moment, and audio cues carry useful warnings during a crisis.246
- Demo bugs are still there.
- Objects spawn inside each other, characters flip when they stand up, and some players see more stutter than in the demo.246
- Some deaths feel unfair.
- Traps hidden under scenery and geysers that throw characters into hazards end runs, and key medicine can be too rare to find in time. Crafting also takes a while to learn.246
- Long-time demo players want more.
- Layers six onward feel bare to several players, and those with many demo hours say the full game adds less than they hoped.246
