Sonic embarks on a planetary race against time...
The sun goes down and a new adventure begins...
In this new adventure, Dr. Eggman finds his old demons, in his quest for world domination. He releases a powerful ray that splits the globe into several continents, but also affects Sonic's condition. The latter must travel the planet and overcome action-packed levels to recover the power of the Chaos Emeralds, for the salvation of the world... and his own!
The world of Sonic is being transformed, thanks to a powerful new game engine that combines finely crafted 2D side-scrolling into vivid 3D environments.
Sonic Unleashed takes everything you love about Sonic and enhances it with lavish landscapes, new powers, an unexpected storyline and, of course, blistering speed!
