The player controls a character (named Hunk Studbuckle) around the platform style screen using the keyboard or joystick. Uniquely, to attack the enemy, the player must temporarily use the cursor keys to move targeting cross-hairs to shoot ghosts and demons (in a similar manner to Operation Wolf), causing the character to stand still. This results in the player requiring to shoot the targets quickly and operate their character to move around the screen before more would appear. In addition to being able to walk, the character can also jump and climb ladders. In addition to enemies to be killed, the environment contains items that can be collected, including 'macho energy' top-ups and 'key' items that unlock further areas. The game is one of few available on the CPC and ZX Spectrum platforms to feature low resolution clips of human speech, although playing them was so CPU-intensive that the game was required to freeze for their duration.
