Sonic Unleashed

As players defeat enemies in both types of stages, they earn experience which allows them to level both Sonic's normal and Werehog abilities, such as speed, strength, life, combat and so on. There are also 3D hub worlds to be explored during both day and night, with different events occurring in each. Sonic can help the townsfolk with tasks for items and rewards, or purchase items from shops using the rings he's collected throughout the stages.

Sonic's buddy Tails also makes an appearance during stages where they fly his plane. During these stages, you must press the appropriate button sequences as they appear to shoot down any oncoming enemies.
