IK was 'International Karate'. I liked 'Way of the Exploding Fist II' on the C64. Gone were the static screens, cue beatutiful vistas of East Oriental theming, caves, dojo's, lush forests. There was not just fights to be had but natural enemies such as waterfalls to negiotiate.
The gaming area seemed huge for its day, it still boasted all 17 (or whatever) moves available in 'Fist 1' and had more of a storyline. I still didnt complete it but lost many an hour to it.
