To open doors and buy guns, grenades, etc, press space. I think you have to have like 1000 points to open doors. WASD or arrow keys to move and click to shoot. If you get touched by the demon thingies you cannot move and are petrified aka dead. good luck. (also there is a little bug where you have to move around a little bit and fire a few rounds some times to get the monsters to spawn).
THIS GAME IS UNDER CONSTRUCTION, SOME INSTRUCTIONS ARE NOT CORRECT. This is the CoD Zombies game by halo79 except I tweaked it a little by changing the map, adding a gun and changing the paint theme on the zombies to black and red to make them...........demons???? Idk well just say they are demons. Also the 22 cal. magnum is completely OP. It also shows the 22 as a shotgun and it kinda shoots like a shotgun. Idk why it does that, but I'm not messing with it.
