An excellent title, in which, three Karateka fight against each other on a beach, trying to be the first to score six points. After every two rounds, there is a bonus game which is either deflecting bouncing balls or kicking away bombs. The game can be played by one or two human players, at least one fighter is always controlled by the computer.
To be honest this is a tough game. It's easy in the first two-three rounds (each round is separated in two fighting events between the three fighters). When passing a fighting round a new karate belt is being given (I only managed to gain the fourth - purple - after playing 100 times or so back to 80s either on 8bits or16bits version!). Between the rounds there is always a bonus round, as previously mentioned.
The C64 version is the best release among all 8bits offering superb graphics and sound! The graphics offer bright colors and more details compared the CPC and ZX Spectrum versions. Backgrounds are cute, although having a single scene (a sunset over the sea etc) with occasionally some animated happenings (birds flying, a Pac-Man would appear, a spider would descend etc)! Note that the game runs way smoother on the C64 version (sprites move faster and smoother) and backgrounds look closer to the 16bit port (Amiga, Atari ST)!
Sound is even better on the C64 version. The in-game music is great while the sound effects here are digitized sounds of karate-style fighting (kicking, punching, screaming etc)! Impressive that is!
