A downloadable game for Windows

Trapped inside a maximum-security prison when the outbreak hits, you are the last one standing. Fight your way through crumbling cell blocks, dark corridors as relentless hordes of the undead close in from every direction.

Survive wave after wave of zombies in this intense round-based survival shooter. Manage your ammo, keep moving, and push back the horde as each wave grows deadlier than the last. How long can you last before the prison becomes your tomb?
