Sonic the Hedgehog is on an adventure unlike any other! Powered by an all-new engine, Sonic Unleashed™ merges classic Sonic gameplay with the latest in next-generation innovation.

At the beginning of Sonic Unleashed, Eggman manages to blast his arch rival with a giant device which has gone haywire, turning Sonic into a beastly werewolf-like creature known as the Werehog.

CrossWorlds' pre-launch Werehog bonus is a treat for older Sonic fans, but many are confused about certain decisions from Sega.
