Even more rooms! This addition to the Boxhead series features not only 8 new rooms to kill or be killed in, but also tons of new features. There are a lot of new weapons and upgrades for you to earn if you can combo-kill the zombies fast enough, a life meter, so you can take several hits instead of dying immediately with one hit, and multiple difficulty levels that the player can select. Try playing on Nightmare mode if you think you're ready for the ultimate challenge!
