Your mission in this awesome game from the Boxhead series is simple, you have to kill all the baddies, Zombies through to the Devil. You only get one life so use it wisely otherwise you will be slaughtered. To earn new weapons and equipment kill the enemy quickly and as many with one shot to increase the Multiplier. As the Multiplier increases you gain new weapons and the weapons you already have are then upgraded. Use the ARROW KEYS to move around. Press SPACEBAR to shoot. Use "Z" or "X" KEYS to select next or previous weapon or select weapons directly with NUMBER KEYS.
