Metro City, 2026. A corrupt mutant group by the name of "Scumocide" plot to control the universe. The hero, Captain Commando assembles a team of three renegades; Ginzu the Ninja, Baby Head, and Mack the Knife; to help him foil Scumocide's plans. This task will not be easy as many of Earh's institutions are infested with Scumocides minions, but strength and persistence runs the team into the crusade.
The player chooses one of these four characters, who must fight their way through an army of genetically engineered super-criminal, traveling through a series of locations such as the bank, museum, circus, aquarium, and several others, right through to a planet called "Callisto", where the evil behind "Scumocide" awaits. All four characters have their own special attacks. Captain Commando can use the power of his suit to shoot electricity through his palms. Baby Head rides around in a mech suit which does more damage. Mack can use short knives. Each location ends with the character defeating a boss before proceeding to the next one.
There are several differences between the SNES and the original arcade version. Blood and gore effects (e.g. burning enemies or halved enemies) and two enemy types were removed. Also one female enemy type has more clothes on and another ones uses bombs instead of acid. A detailed list of changes can be found on schnittberichte.com (German)
