It's not just racing, it's racing transformed!

Sonic and the All-Stars cast line up on the starting grid once again to battle for supremacy in the ultimate race. Compete across land, water and air in incredible transforming vehicles that change from cars to boats to planes mid-race. Master your driving skills as you drift, barrel role and boost to overtake your rivals, or use your weapons tactically and unleash your All-Star move to gain the winning advantage.

It's not just your fellow racers you need to watch out for, as the road falls away beneath you, or the river runs dry, new routes emerge and your vehicle transforms to take advantage of the terrain. Discover alternative routes and short cuts as you perfect the course in this adrenaline fuelled dash to the finish line - racing will never be the same again.

• Dynamic tracks: Take to land, sea & air as you race through 16 dynamically changing courses inspired by SEGA's illustrious gaming history. Discover alternate routes, find new power-ups and avoid emerging hazards as you race to victory - every track feels different.
• Choose your racer: Race as over 20 legendary All Stars. The starting line-up has been transformed as new iconic characters from the world of SEGA join the race. What other game sees a hedgehog battle it out against a monkey, a sky pirate and an axe wielding dwarf!
• Fully transformable vehicles: This is no ordinary race. Each character is equipped with their own unique vehicle that can transform into a car, boat and plane to take advantage of the changing terrains. Each vehicle handles differently and players must master all three to triumph.
• Tools of devastation: Utilise an arsenal of devastating weapons which require skill to aim, shoot, evade and block. The All-Star Moves also return, this time the more daring and stylishly you race, the more your All-Star meter increases allowing you to unleash carnage on your opponents!
• Ultimate gaming experience: Old rivalries can be settled and new ones created in up to 8 player online. Journey through the All-Stars' world to take on a huge range of modes and challenges, including Grand Prix, Battle arenas and an incredible world tour.
