Game Description:Sonic Riders returns with another insane racing challenge that brings all the action you'd expect from the series, but leaves gravity behind! Race at the speed of light on 16 courses that range from futuristic city streets to the outer reaches of space. Choose from 19 colorful characters, including Sonic himself, and hop aboard one of 60 vehicles, all ready to pull off stunts you have to see to believe. Compete with up to three friends in three multiplayer modes. And since you have the power to control gravity, you'll carve a mind-blowing path to the finish line by cracking through walls, opening black holes, and much more.
