In this game you play the part of one karateka who fights against 2 others (1 can be controlled by a second player), in order to gain points and belts. There are also some bonus sub-games where you must be quick in kicking away bombs or by deflecting balls using a type of shield.
IK+ was one of the best and more fun to play karate games during the 8bits and 16bits home computers era. Win points, get the highest belt and be the new master!
The Atari ST version offers the same quality in details as the Amiga version (but with fewer no. of colors), and the character animation is nice and smooth. The background image does not change and is a wonderful sunset near a temple!
Much like the Amiga version, the Atari ST version features digitized sound FX, punches and kicks taken from karate/fighting movies and cries that remind us of Bruce Lee. The music score, composed by Rob Hubbard, was just a conversion from the 8bits Amstrad computer, with 3-channel chip sound.
