SEGA has sent out a few official details on Sonic Generations for 3DS, a week after a bevy of information on the game was pulled from Nintendo Power magazine.
The game is set across three “defining eras from Sonic the Hedgehog’s twenty year history,” and contains 3D levels designed exclusively for the handheld.
Environments based on iconic levels from previous Sonic titles will include an exclusive unlockable Special Stage, and the game will also make use of StreetPass by allowing players to collect new content and unlock bonus material each time they pass another player.
In addition, a new two-player versus mode as been added to the 3DS version.
Sonic Generations will be made available on 3DS, PC, PS3 and Xbox 360 in November.
