Sequel of "International Karate" (more moves can be performed by the fighters).
You (as a karateka) fight a series of combats trying to earn the next belt (white, yellow and so on up to black) proving your mastery of the martial arts.
Every match sees three fighters involved: each one scores "hits" performing effective moves against any of the two opponents. When a fighter scores five "hits" (or the time ends), the one with the poorer score is eliminated.
A mini-game (use a shield to deflect bouncing balls thrown at you by both sides of the screen at increasing speed) offers a small diversion between the matches.
