Sonic is finally back the way he deserves, in the game that made him so famous in the first place. Relive the good old days or get a feel for retro gaming as you help Sonic fight the evil Dr. Robotnic and collect the Chaos Emeralds!
Saving allows you to re-trace if you don't have the time to beat the whole game or if you can't beat that one level. Achievements range from beating the game to collecting all six Chaos Emeralds. No add-ons or extras besides those two - Sonic is back in his original form.
