A horror co-op extraction builder set in a scorched wasteland where everything burns. Descend with your friends into shifting ruins, rip out furniture, and scavenge for loot before the Corrupted close in. Make it back alive, then rebuild the Outpost to better your chances for the next run.

The loop is simple to describe but demands coordination:descend into the ruins with your friends,rip out furniture and scavenge loot, then escape before the Corrupted catch you. Whatever you bring back goes toward rebuilding the Outpost, which improves your odds on the next run. The ruins are described as shifting, so expect routes and layouts to change between descents.
