About Casualties: Unknown
Casualties: Unknown is a 2D survival simulation about expeditions into a hostile cave system on an alien planet. Runs center on reaching lost cargo, choosing what to carry, and deciding when to retreat or continue.
Exploration connects movement, crafting, and body management. Injuries, blood loss, infection, and scarce supplies can compound, while each cave layer brings its own hazards. This library organizes practical guides around those systems, the game’s characters, equipment, and endings.
