Human Killing Machine

Human Killing Machine is a one-on-one fighting game where you control Kwon, a Korean kickboxer wearing boxing gloves, on a quest to prove his supremacy across five countries. Fight your way through ten bizarre opponents, including a rifle-wielding Soviet soldier, his attack dog, Amsterdam prostitutes, a bullfighter and his bull, a bottle-throwing German waiter, and finally terrorists in Beirut. The game uses a knockdown system instead of traditional rounds. Opponents' health regenerates, there is no guarding or special moves, and you have only basic punches and kicks. Touted as an unofficial sequel to Tiertex's conversion of Street Fighter, it uses a similar engine but with new characters.

ZX Spectrum

Released in 1988 by U.S. Gold, the ZX Spectrum version was generally well received, unlike other ports . Your Sinclair awarded graphics 9/10, praising the "big - nay, hooge - sprites" and excellent background art . Sinclair User (78%) noted "slick arm and leg movements - maybe the best I've seen in this sort of game," adding that graphics may be slightly better than Street Fighter . Crash (73%) called scenery "really beautiful" with "large characters well drawn and animated," deeming it lacking originality but still very addictive . The limited move set was the main drawback due to memory constraints for the detailed visuals. Unlike the sluggish 16-bit versions, the Spectrum version offers responsive controls and fair difficulty, making it arguably the best conversion of this flawed fighter .
