Survive the wasteland with a friend, and battle against other players in epic battles, using vehicles, turrets and more, all while surviving against the zombie attack.
Co-op will mean you and your friend(s) can form a faction, and set up at a base.
Multiplayer forms in like single player, but there will be other players amongst the zombies, and you will have to fight them to get the things you need to survive.
well nice one =)
