Explore breathtaking new tracks like Sonic Seaside Hill, Curien Mansion, and Blizzard Castle as you race at high speed around medieval castle walls, beneath lush rainforest canopies, and through bustling cityscapes to the finish line. Compete in your unique character vehicle against a selection of 20 challengers, including Ai Ai from Super Monkey Ball, Amigo from Samba, and the evil Dr. Eggman. Stay ahead of the pack by dodging traps and using outrageous character maneuvers like the invincible Super Sonic, the Banana Blitz Attack of the Monkey Balls, or Tails' wild Tornado to send any vehicle flying. But if you get knocked down and broken, it's not over yet. Recharge your vehicle with power-ups to get back in the race, and keep an eye out for secret shortcuts that will give you an edge on your way to victory.
