Game Description:Fifteen years after making his debut as Sonic the Hedgehog, the famous blue creature races into next-generation gaming! In his first trip into the world of humans, Sonic befriends the princess Elise. She's kidnapped by Dr. Eggman in a plot to destroy her kingdom, and it's Sonic to the rescue! The PS3's capabilities combine light bloom and motion blur effects, delivering a feeling of speed that's dizzying, even by Sonic standards. Encounter friends and foes from the entire Sonic franchise, plus a new, powerful enemy, Silver. The game's divided into Town Stages to explore and Action Stages to shred. Up to four friends can play as Sonic (and his friends) online.
