Casualties: Unknown launches Monday, Nov. 9 at 6am PT, 8am CT, 9am ET, 2pm UTC, and 3pm CET on PC. Orsoniks developed this psychological horror simulator that blends exploration and survival gameplay.

The game places players in a harsh underground world where they manage injuries through a simulated limb and cardiovascular system. Players must bandage wounds, fight infections, and stabilize blood loss to survive. Crafting tools from resources allows players to repair themselves and descend deeper into a cave system on an alien planet's core.

Each level presents distinct risks, and careless decisions lead to death. Character traits affect each run, with three different characters available. The game features 11 levels and over 300 items to discover.
