SEGA today announced Sonic Unleashed, coming late this year on PS2, PS3, Xbox 360 and Wii from Sonic Team, the latest title featuring everyone's favourite speedy blue Hedgehog will yet again do battle with evil Dr Eggman by collecting lots of things whilst running very fast.

Sonic Unleashed is built on a powerful new "Hedgehog Engine", which introduces seamless 3D to classic 2D camera transitions, whilst delivering a rich and expansive world with multiple paths to choose from. Under development for three years, the Hedgehog Engine produces a visually rich next generation look and feel with elements of classic Sonic gameplay mechanics. The Hedgehog engine will help re-define the gameplay experience for Sonic fans and newcomers to the franchise alike.

"By combining rich and vibrant scenery with dynamic viewpoints Sonic Unleashed will provide an immersive 3D experience whilst keeping alive the 2D gameplay elements and fantastic worlds that Sonic fans know and love" commented Gary Knight, European Marketing Director for SEGA Europe. "In addition to this classic Sonic gaming experience, when darkness sets in Sonic Unleashed players will be able to experience a completely new way to play as Sonic… making this his most exciting adventure yet!"
