In this new adventure, Dr. Eggman is up to his evil antics again, in his quest for World domination, he unleashes a powerful ray that divides the world into several continents and transforms Sonic into a beast-like state. Sonic must travel across the globe, completing action-packed stages to retrieve the power of the Chaos Emeralds to ultimately save the world and himself!
Sonics world has been transformed, courtesy of a powerful new game engine that delivers the tight gameplay of a 2D sidescroller in stunning, picturesque 3D environments.
