Plot
In the year 2215 AD, the world is ruled by a corporation called Centro-Holographix ('Metro-Holographix' in some versions), which captures unwilling humans and replaces them with holographic versions which carry out its will. Two of these agents, Hammerfist and Metalisis, have malfunctioned and turned against Centro-Holographix, seeking to destroy it and liberate their original human forms. As part of the malfunction, the two holograms have been merged into a single being who can transform back and forth between their two forms at will. They initially escape from their storage pods in a laboratory at the bottom of the ocean and must fight their way out, after which they must cross the ocean, battling a variety of undersea creatures as they go. Finally, Hammerfist and Metalisis reach a destroyed city and penetrate the Centro-Holographix facility, confronting and eventually destroying the corporation's ruler, a being known only as The Master. Hammerfist and Metalisis, separated into their original bodies, escape Centro-Holographix for good.
