god is this game a pain in the a** to beat with 1 person. the zombies just dont back off and if you miss a shot, there goes 1/3 of your health

its a very fun game (and free to download, making it better)

so if your bored of the high graphics, the 3D look and what the zombies to be blue (or like me, cant be f*ed to load all the updates) , play Pixel Force Left 4 Dead

(and say here if you like it or not, and if u finish it)
