What you need to do is press 1 to switch your gun to a pistol, 2 for a shotgun and 3 for a mini-gun. Use the up-down-left-right arrow keys to move. Left and Right are to rotate and back. Forward is to move forward. Have fun and leave a comment if you enjoy it!
So, the story of the game is that you are a space explorer and you got lost on Mars, and you are being attacked by zombie Martians, and you must defend yourself with the weapons you have. GOOD LUCK!!! This game was created by Archie Timms. Massive thanks to everyone at CoderDojo Clonakilty.
