Sonic Unleashed - Trailer

Sonic Unleashed, also known as Sonic World Adventure in Japan, is an upcoming video game in the Sonic the Hedgehog series. The name was trademarked by Sega on March 12, 2008. Screenshots of cut scenes, artwork, and a video were leaked ten days later; the title was then officially confirmed by Sega on April 3, 2008 with a small selection of screenshots and an updated video.

The gameplay style is markedly different when compared to recent games. It will focus on 2D side-scrolling platform gameplay, rendered with 3D visuals, as well as behind-the-back, third-person stages. Gameplay will seamlessly transition between these two styles.
