ZOMBIES ARE INVADING THE MOON!!!! Use the X key to put land mines, and if a zombie touches it he dies. Click to shoot, and WS or arrow keys to go forward or backward. Use the mouse to guide your shooter dude. Press Q to go to machine gun fire (Hold the mouse) and E to return to the default gun. FYI: The "IMPOSSIBLE" mode sets the zombies so big, you immediately die!
