Descent, adapt, and survive in an unforgiving cave exploration survival simulator
Casualties: Unknown is an unforgiving cave-exploration survival simulator where survival is never guaranteed, featuring a fully simulated limb and cardiovascular system in which every injury has real consequences. Bandage wounds, manage infections, and stabilize blood loss before losing consciousness. Players are thrown into the depths of a hostile alien planet, tasked by unseen captors with retrieving lost cargo across 11 increasingly dangerous layers.
The Steam demo is now live, dropping players straight into the depth, play 5 of the 11 layers, featuring ALL core mechanics and systems planned for the full launch. Test your limits against its brutal survival systems, where every decision matters and mistakes are rarely forgiven.
Oro Interactive has released a new trailer giving a closer look at the game’s layered cave exploration, fully simulated cardiovascular system, and the constant pressure of descending deeper into the layers.
Survive a Harsh World
Each layer introduces new environmental threats that demand constant adaptation from the player. From unstable terrain to unpredictable hazards, survival depends on learning quickly and making the right decisions under pressure.
The deeper you go, the less forgiving the world becomes. What worked before may no longer be enough, forcing you to rethink your approach with every descent.
Simulated Limb and Cardiovascular Systems
In Casualties: Unknown, injuries are unavoidable, and survival depends on how you handle them. You’ll need to respond quickly to damage, managing blood loss, preventing complications, and staying conscious long enough to recover.
Your mental state also plays a critical role in your survival. Prolonged stress and despair can make every situation harder to manage, turning small mistakes into fatal ones.
Explore at your Own Risk
You are not the first to attempt this descent, and you won’t be the last. Previous expeditions have left behind valuable loot, scattered throughout the depths.
However, not everything you find is safe. Locked containers, abandoned pods, and hidden caches may help you survive, or kill you instantly if you’re careless.
Uncover the Truth
Beneath the layers lies something more than just lost cargo. The deeper you go, the more questions begin to surface about the purpose behind your mission.
What waits at the bottom, and what happens to those who make it there? Few have made it far enough to find out.
