Sonic Unleashed sees the hedgehog hindered by a new 'Werehog' form at night, and travels to both return to his normal form and stop Dr. It was launched for the Xbox 360, Wii, PlayStation 2, and PlayStation 3 as a reformed and reworked take on the Sonic franchise, likely to counter criticism of the earlier 2006 Sonic the Hedgehog game. Sonic Unleashed, called Sonic World Adventure (ソニック ワールドアドベンチャー) in Japan, is a video game released as part of the the Sonic the Hedgehog series in late 2008.
