Sonic will find himself in a race against time and faced with an unusual situation that will challenge him in ways never before seen in Sonic Unleashed from SEGA for the Microsoft Xbox 360.

Having been broken apart by the evil Dr. Eggman, it's up to Sonic to put the pieces of the world back together again by retrieving the power of the chaos emeralds.

Features:

• Alternate between 2D and 3D views as Sonic goes on a quest to save the world.
• Bash enemies with the slower, stronger alter ego Sonic the Werehog.
• Reach blistering speeds through nine multi-path game worlds
