A secret laboratory has gone dark. An experimental virus has escaped, the staff have become bloodthirsty infected, and the security systems have locked the entire complex from within. There is only one way out: load your weapon and fight your way to freedom.
Explore dark corridors, unlock sealed rooms, and survive zombies attacking from every direction. Collect valuable parts and key items, reach checkpoints, and grow stronger with every battle. Your soldier fires automatically, but survival depends on your movement, reactions, and ability to avoid being surrounded.
Unlock and upgrade nine weapons, including a shotgun, crossbow, flamethrower, grenade launcher, rocket launcher, and other deadly tools. Defeat massive mutants, combine powerful upgrades, and reach the exit.
Can you escape the laboratory alive?
How to play
Move your character using WASD or the arrow keys. On mobile devices, touch the screen and drag in the desired direction. The left gamepad stick is also supported.
Your soldier automatically aims and fires at the nearest infected enemy. Keep moving, maintain your distance, and do not let the horde surround you.
Approach dropped items to collect them automatically. Stand inside the marked zone near a blocked passage to deliver the required resources and open the way forward.
Destroy zombies, gain experience, choose upgrades, and switch between unlocked weapons. Explore the laboratory, find key items, and reach the exit.
