Karate Champ on the Commodore 64 is a one-on-one tournament fighting game based on Data East’s arcade hit, where you play a white-gi karateka squaring off against a red-gi rival under the watchful eye of a referee. Instead of a draining energy bar, bouts are scored like real competition: clean blows and well-timed kicks or punches earn half- or full-points, and the first fighter to reach the required score wins the match and advances. Using a single joystick plus fire for different directions and strikes, you string together high and low kicks, punches, back-steps, and jump attacks, then break things up with occasional bonus stages like dodging charging bulls or smashing objects. The result is a slower, more tactical martial-arts game that feels closer to point-scoring sport karate than a wild button-mashing brawler.
