In this post-apocalyptic survival game, you wake up deep inside a bunker devastated by catastrophe. The rooms are shrouded in darkness, resources are scarce, and the horrors lurking behind every door won't give you a break.

Explore the bunker room by room in a procedurally generated world where every run is different. Scavenge supplies, find or craft improvised weapons, and face off against enemies in a turn-based combat system where every decision could mean the difference between life and death.

You wake up as the last survivor trapped in the depths of a military bunker infested with zombies. As the only one immune, after too much time alone, you decide to explore and fight one last time to reach the surface. If there is still a world to return to.
