Zombie Survival is a map with a simple premise.You’re stuck in a house with zombies. A lot of zombies. So there we go. You can try to survive, or try to be eaten. Either way you’re going to have a whole lot of fun hacking, slashing and screaming your way through waves of zombies, skeletons and spiders – because no day is complete without some jerk levitating through an open window and trying to end you.
