The story so far
What we know about Casualties: Unknown
Casualties: Unknown is a cave-exploration survival simulator developed by Orsoniks and published by Oro Interactive. According to the Steam page, players descend through 11 layers of a foreign planet as expendable test subjects, sent by their captors to retrieve lost cargo while surviving a range of hostile environments.
The game leans hard on bodily simulation: the store page describes an entirely simulated cardiovascular and limb damage system, so wounds and blood loss have to be treated. Crafting, exploration of procedurally generated environments and character stats (Strength, Intelligence and Resilience) round out the loop. A demo is available on Steam, and the game is listed only with a planned 2026 release, without an exact date.
