The undead have taken over! Load up and fend them off for as long as you can, and protect your squadmates too as you fight for survival! Flag down helicopters by building a fire, or roll around with your tank to take out large enemies. Customize your player, choose your weapons, and try out randomly generated levels. You have plenty of ammo for all these zombies; why don't you share it with them? ;)
