Ka•Ge•Ki, or Ka•Ge•Ki: Fists of Steel as its North American Sega Genesis port was called, is a boxing game developed by Kaneko and published by Taito for the arcade. The goal of the game is to fight a series of opponents in a run-down apartment building taken over by a criminal gang. Each defeat brings the protagonist Ken closer to the boss at the top of the tower.
The game was ported to the Sega Genesis by Hot-B, a company that had already ported over Taito's Insector X for the system the previous year. Sage's Creation, a company with connections to Hot-B, published the port in North America.
