Who it's for Survival players who want every wound to matter.
Casualties: Unknown drops you, one of thousands of test subjects, into the caves of an alien planet to bring back lost cargo for your captors. The planet has 11 layers, each with its own dangers, and nobody expects you to make it back.
The hook is the body simulation. Limbs and blood circulation are simulated, so you bandage wounds, fight infections and stop the bleeding before you pass out, and a gloomy mood makes everything harder. There are three characters, about 300 items, and loot and danger settings on the main menu. Steam's content note mentions depression, violence, dismemberment, drug use and self-harm.
