Set across three defining eras from 20 years of Sonic the Hedgehog video game history, the instantly recognizable environments of Sonic Generations have been re-built in stunning HD and are now playable in both classic side scrolling 2D from 1991, as well as modern 3D style found in Sonic's most recent adventures.

Play as both Classic Sonic and Modern Sonic in the ultimate Sonic experience. Master the moves of each character as they race through each environment on their own specially designed track.
