Why it matters
The pitch is a survival sim that tracks the body past a health bar, and the tension claim rests on one detail: gear left by earlier explorers is not necessarily helpful.

Casualties: Unknown sells itself on a body that keeps its own accounts. Limbs, the cardiovascular system and mental state are simulated, and bleeding, infection and untreated injuries can cost the player consciousness. Treatment is not issued; players craft tools and first aid from what the caves yield.
Orsoniks also builds in multiple characters, parameter growth and hundreds of item types, and the loop is meant to run through repeated deaths on the way to deeper layers. The PC release on Steam carries a 15 percent discount through November 24, and a free demo is available.
