Human Killing Machine

The player must defeat computer controlled characters from around the world in round-based one-on-one combat. The game is based on the engine from each system's Street Fighter port, with the time limit removed, and an energy recovery system.

The following characters are featured in the game:

At the time of release, the ZX Spectrum version of the game was generally well received, scoring 9/10 for graphics in Your Sinclair, who added "Possibly because of the memory used for the excellent background graphics and big - nay, hooge - sprites, the range of moves available in battle seemed relatively limited. It was, however, still fairly easy to beat opponents". The game scored 78% overall in Sinclair User, who summed it up with "backgrounds are static, but detailed... main graphics are nicely animated with slick arm and leg movements - maybe the best I've seen in this sort of game.

The graphics may even be slightly better [than Street Fighter]". The 73% review in Crash stated "The scenery's really beautiful and the large characters are well drawn and animated", and thought it was "lacking in originality, but still very addictive".
