Sonic Unleashed is a platform game for Xbox 360 that features two distinct gameplay styles. During the day, players control Sonic in high-speed platforming levels, emphasizing his iconic speed. At night, Sonic transforms into the Werehog, introducing a slower, brawler-style gameplay where players engage in combat against various enemies in a quest to restore the Gaia system.
Gameplay in Sonic Unleashed focuses on two modes of platforming play: fast-paced levels that take place during daytime, showcasing Sonic's trademark speed as seen in previous games in the series, and slower, night-time levels, during which Sonic's Werehog form emerges, and gameplay switches to an action-based, brawler style of play, in which Sonic battles Gaia enemies
