Introducing Miles Tails Prower to the Genesis Megadrive in the role he was created for, the game was released worldwide on November 24th, 1992. Dubbed Sonic 2sday, the simultaneous release was an unusual move for the time. The game eventually replaced the original Sonic the Hedgehog as the default pack-in title for the Mega Drive, being bundled with the redesigned Mega Drive II model.
