Single player open world zombie killing, all packed into this arcade sized game. From Microsoft based developers Undead Labs, this game has you playing as several different characters, upgrading and changing your safehouse or safe haven multiple times. Being a very detailed and immersive game, there are hundreds of different weapons to choose from and vehicles to drive. This is a game that you don't want to dismiss simply because of its size. It's one of those "good things come in small packages" situations.
