See a whole new side of Sonic the Hedgehog in Sonic Unleashed! When Dr. Eggman cracks the world into pieces, Sonic races to put it back together. But there's a twist! When the day ends, a new adventure begins. At sunset Sonic changes into a werehog and the focus shifts from speed to strength. Sonic's usually blisteringly fast gameplay gets throttled up thanks to a freshly built Hedgehog Engine that delivers new levels of Sonic speed and maneuverability. Use the Quick Step to dodge left or right without losing speed, carry top speed through turns with Speed Drift, trigger a Sonic Boost to blast beyond top speed, and more.
