Sonic the Hedgehog is on an adventure unlike any other. Powered by an
all-new engine, Sonic Unleashed blends classic Sonic gameplay with a variety of
in-game perspectives to create an entirely new and unique gaming experience.
The evil Dr. Eggman has broken the world apart, and it's up to Sonic to put the
pieces back together again by retrieving the power of the chaos emeralds! In
doing so, Sonic will find himself in a race against time and faced with an
unusual situation that will challenge him in ways never before seen.
