Sega mascot Sonic the Hedgehog celebrates his 15th anniversary with an all-new adventure set in a human world. The action takes place in a land called Soleanna, whose radiant princess (voiced by actress Lacey Chabert) is abducted by Dr. Eggman as part of his evil scheme to destroy the land. The result is a fast-paced romp through a mysterious kingdom, as Sonic befriends new characters and unites with past favorites while trying to stop Eggman and his robotic minions. Similar to the format introduced in 1999's Sonic Adventure on Dreamcast, gameplay is divided into two distinct phases. While in town, players will be able to explore their surroundings, engage in mini-games, and interact with colorful characters. Outside of town are action sequences showcasing Sonic's trademark speed and special moves, with dynamic environments built around a new physics engine made possible by the advanced capabilities of the PlayStation 3 and Xbox 360 consoles. High-speed cooperative and competitive challenges are also included for up to four players. ~ Scott Alan Marriott, All Game Guide
