A sequel, Sonic & All-Stars Racing Transformed, was released in 2012.
The game plays similarly to other kart racing games such as Mario Kart, with characters collecting power-ups to boost their speed or hamper their opponents. Like Sumo’s previous Sega game, Sega Superstars Tennis, each character has a “Star Move” unique to them, such as Sonic transforming into Super Sonic, or Shadow turning into Super Shadow, that they can use against their opponents. The game has multiplayer options for up to four players on split-screen and eight players online.
Vehicles are separated into three different categories: car, bike, and hovercraft. As the terrain on the tracks will vary, vehicles can be either assisted or hindered by the surfaces they drive upon. Cars vary in speed and weight, with some performing better on some terrains than others. Bikes have fast acceleration and can perform wheelies for a speed boost, but can be easily bullied by heavier vehicles. Hovercrafts are not affected by any terrain and are able to perform multiple boosts after a jump, but they have poor handling and have low acceleration. All of the vehicles also have their own specific engine sounds. Sega Miles that can be spent in the in-game shop to unlock additional content such as characters, tracks, art, and songs.
The game has customizable multiplayer options for up to four players on split-screen and eight players online, including Free Races and Arena Modes. There is also a Grand Prix, Time Trial, and Mission mode.
