Play James 'Buster' Douglas Knockout Boxing Online

James 'Buster' Douglas Knockout Boxing came out for the Sega Master System in 1990, a Sega release that put you right in the middle of the heavyweight action. It was a straightforward boxing title for its time, one of the few that tried to capture the sport on the 8-bit hardware, and it didn't try to overcomplicate things with excessive frills or a deep career mode.

You control a boxer working his way up the ranks, with the main goal being to win matches and eventually claim the championship. The gameplay involves moving around the ring, timing your jabs and hooks, and looking for openings to land a powerful charged punch. Between fights, you can spend points to slightly improve your boxer's attributes like power and stamina, which gives you a small sense of progression. The pacing is deliberate, matches can feel a bit slow, and the difficulty has a noticeable spike as you face higher-ranked opponents. It feels like a simple, sometimes clunky simulation of the sport that requires patience to master.
