Sonic & All-Stars Racing Transformed

A secret organization called Fata Morgana is developing a weapon that is capable of killing or wounding two-thirds of the world's population. A super-national group of combat experts from all over the world called Project Blue has been established to counteract Fata Morgana's evil doings.

The gameplay involves collecting power-ups and items to gain an advantage over opponents, as well as using special abilities and transforming vehicles to outmaneuver rivals.
