Survive a vertical prison with no way out. Team up with other players to scavenge resources that descends one level each day. Manage your hunger, repair machinery, and find a way to escape before the security system eliminates you.
O-COP
SteamO-COP is a multiplayer social survival horror game set inside a towering vertical prison. Inspired by The Platform, it drops you into a world where food is scarce, every floor is a gamble, and the people around you are your greatest threat. You can build alliances, make trades, and plan your escape or you can take what you need and leave others to starve. Every round, the rules are the same. Every round, the outcome is different.
A Living, Shifting Prison
Each day begins with a random reshuffle. Your floor changes. Your neighbors change. A smart descending platform delivers food to every level but there is never enough for everyone. Learn which floors get fed first, and plan accordingly.
Survive on Your Own Terms
Manage your Health, Stamina, and Hunger to stay alive. Sprint when you need to. Eat what you find. Drop too far and you pay for it. The prison does not care how you survive only that you do.
Inventory, Items, and the Soul System
Carry up to three items, pick up and throw objects, and eat food to restore your vitals. Collect wandering souls and sacrifice them at the Pillar to earn Soul Points a currency you spend at the Shop to gain an edge over other prisoners.
Deal, Deceive, or Dominate
Use the secure trade system to exchange items with other players, with a built-in countdown to keep things fair. Talk your way through deals using real voice chat via Steam Voice push-to-talk. Every interaction is a choice between cooperation and betrayal.
Escape or Watch Others Try
Collect Escape Parts scattered across the floors, repair the Assembly Machine, and unlock the exit before time runs out. If you die before you make it out, you enter Spectator Mode switching between survivors as the final round plays out.
