Casualties: Unknown (v1.0)

Casualties: Unknown turns survival into a tense descent through the layered depths of an alien world where every expedition feels like a medical emergency waiting to happen. Rather than treating health as a simple bar, it makes bleeding, broken limbs, circulation, infection, and mental strain central to the struggle. The mood is oppressive and lonely, with useful supplies scattered among environments that can kill an unprepared explorer just as quickly as any hostile threat. Reaching the bottom is only part of the goal; the mystery of what waits there gives each risky push onward a grim sense of purpose.

Runs revolve around scavenging, assessing danger, and using whatever materials the caverns provide to stay alive long enough to descend another layer. Wounds demand specific attention: bandages slow blood loss, treatment helps contain infection, and damaged limbs can compromise how effectively a character travels or survives. Crafting turns plants, loot, and found resources into practical tools and emergency remedies, while Intelligence, Strength, and Resilience improve over the course of a run. Three playable characters offer different approaches, and adjustable loot and danger settings let players tune the balance between punishing scarcity and a more forgiving learning experience.

Its detailed bodily simulation is the major hook, making a bad decision feel consequential without reducing survival to simple hunger meters and item durability. Eleven distinct layers and roughly 300 discoverable items give exploration a strong experimental edge, since an apparently valuable find can create a new problem or lure players into a fatal situation. Casualties: Unknown suits players who enjoy the systemic tension of roguelike survival games such as Caves of Qud or Darkwood, especially those who like adapting under pressure rather than mastering a fixed combat routine. Newcomers should expect a harsh learning curve, but veterans of unforgiving survival sandboxes will appreciate how much every injury, tool, and descent matters.
