Via the official Sonic Tuenti, SEGA Spain has revealed the box artwork for the European Sonic Generations PS3 and Xbox 360 Special Edition. The cover is lenticular and switches between Classic Sonic and Modern Sonic. Boasted on the cover is exclusive DLC for this edition of the game, which as we know from UK retailer GAME is the Casino Night Zone pinball mini-game.
You can view both PS3 and Xbox 360 versions of the box art below.
Thanks to frokenok3 at the SSMB for the heads up!
