A Sonic Generations special edition box has been spotted on the GAME website.
The high-street retailer is offering the bundle for £37.99, for which you'll get an exclusive stage, avatar costume and console theme.
Purchasers will be able to play through the iconic Casino Night Pinball Stage from Sonic The Hedgehog 2, give their avatar a 'super transformation' make-over and deck out their console with a Sonic paintjob.
GAME's offering the standard version of Sonic Generations for £32.99.
