Sonic Megamix 5.0
Sonic Megamix, which is short for Sonic the Hedgehog Megamix, is a work-in-progress modification of the original Sonic the Hedgehog video game for the Sega Mega Drive. It was created by Team Megamix and has since been moved to the Sega Mega-CD. In the game, you can choose to play as Sonic the Hedgehog, Mighty the Armadillo, Shadow the Hedgehog, Miles "Tails" Prower, or Knuckles the Echidna. It's a big change from the original game, with new art, music, skills, layouts, and other things.
