George Foreman's KO Boxing is a 1993 boxing video game developed by Beam Software on the Sega Mega Drive. A version was developed on the Sega Game Gear and Sega Master System but was basically a repackaged version of Heavyweight Champ by Sims.


In the Mega Drive version the player takes on the role of George Foreman who must defeat other boxers to become the heavyweight champion. The gameplay takes place from a behind the character perspective.

As was typical for many boxing games from around this period, George Foreman is the only "real world" boxer in the game, with all of his opponents being fictional.



The Mega Drive (and SNES) version was originally supposed to feature digitized boxers, but near the end of development, one of the graphic artists demanded that the sprites were hand-drawn.


The Mega Drive and Super NES versions of George Foreman's KO Boxing are broadly similar, however the Super NES version capitalises on the system's larger colour palette and features a number of graphical effects (namely screen transitions) not present in the Mega Drive version. Both versions run with a 256x224 screen resolution at all times, despite the higher 320x224 mode being available on Sega's console.

The Super NES version can also handle digitised speech more effectively - all other sound channels fall silent on the Mega Drive when somebody talks, while the Super NES continues to produce crowd noise and music when this occurs.

The gameplay remains unchanged between both versions.
