He's back! Everyone's favorite blue hedgehog, Sonic, and six of his friends (and enemies) have come with their souped-up vehicles to battle it out on the track! There's more to this than just speed and control, as these zany racers will resort to just about anything to slow each other down. Choose one of the seven characters -- Sonic, Knuckles, Tails, Dr. Robotnik (known to his fellow racers as the "Eggman"), Amy, Fang or Metal Sonic -- and battle the clock (and sometimes Mother Nature) on any of 18 courses. Enter the Chaos GP, where you pick a character and test your skill and trickery against three other drivers over six courses. Or, for great head-to-head action, get a friend to join you and try the Versus mode. Once these drivers hit the track, those who were friends become rivals! They'll use every trick in the book (and a couple that aren't) to put each other out of the running. Be ready for anything......Its the second annual "Chaos Grand Prix" and this time EVRYONE'S pulling out all the stops!!!!
