There is barely any true zombie games out there... Dead Island, Left 4 Dead and The Walking Dead are closest, with TWD actually being ahead in terms of true zombie feel. But if you want to play an awesome zombie game, the Last Stand games (Flash game) are best imo. Red Dead Redemption has a DLC that is pretty fun but the controls aren't great for that type of gameplay.
