Gameplay
Clash at Demonhead is a Metroidvania-style platformer. The protagonist is Billy "Big Bang" Blitz, who shoots, runs, and jumps around in an open-ended world. He starts with only a pistol, but various upgrades and power-ups can be purchased with Force. The game is non-linear with approximately 40 levels (routes) to go through.

Plot
Billy is a sergeant in S.A.B.R.E. (Special Assault Brigade for Real Emergencies) While he is at the beach with Mary, his girlfriend, he is contacted by S.A.B.R.E. to rescue Professor Plum, the inventor of a Doomsday Bomb that can destroy the world. Tom Guycot has abducted him, and Billy finds out that the bomb is controlled by seven medallions in the possession of seven governors of Demonhead. Billy later meets Michael, who tells him about a sprite. The sprite tells him about a hermit, who upon being rescued by Billy teaches him many force powers. Later, while looking for medallions, Billy experiences an odd discomfort in his head. Billy discovers that the discomfort was caused by a demon failing to mind-control him. It cannot control Billy, but the demon manages to control Michael. The demon tells Michael to ensnare Billy by telling him a legend about how a magic stone can yield great treasure if brought to a certain location. The magic stone actually is a key to free the demon from under the mountain it is trapped in. The demon then escapes and kills Tom Guycot and takes his medallion. The hermit tells Billy that the demon can only be killed with the Sword of Apollo. After eliminating the demon, Billy tries to rescue Plum, but realizes the bomb is already complete. It is revealed that the bomb is the product of an alien race's technology, the same race that created humans. They attempt to use the bomb to destroy the humans they have grown frustrated with. Billy succeeds in defusing the bomb with the medallions, and the world is saved.
