Decap Attack

Decap Attack is a 1991 platformer where you play as Chuck D. Head, a headless mummy sent by Dr. Frank N. Stein to defeat the demon Max D. Cap and his monster army. The game is a modified version of a Japanese game and features comical Halloween-themed graphics as you guide Chuck through side-scrolling levels. You attack enemies by extending his head or jumping on them, and can also find power-ups like a boomerang skull and various potions that grant invincibility or clear the screen of enemies.
