From The Lost Media Wiki
Michael Jordan: Chaos in the Windy City is a 1994 SNES platform action video game that was developed by Electronic Arts and published by Ocean. A Sega Genesis version was also in works, but was cancelled due to the poor sales of the SNES version. The player controls Michael Jordan on a quest to save the rest of the players for an All-Star charity game from the aliens.
A prototype box artwork and the cartridge exists and is yet to dumped.
