Disney Pixar: Cars - Platinum (PSP)

Cars is an arcade racer based on the Disney/Pixar movie of the same name. The player can unlock and drive vehicles through numerous tracks and environments from the world of Carburetor County. The game features authentic voiceover talent from the movie and provides a variety of ways to race (Story Mode with elements from the film, Grand Prix where you unlock tracks, Custom Race and Postcard Races with collectibles).

Unlike the console versions, there is no free-roaming and there is less focus on the story. Evil cars have taken over the tracks and Lightning McQueen and his friends have to defeat them, loosely based on elements from the film, in 25 events. WiFi adhoc multiplayer is supported for up to four racers. Three game modes are available in multiplayer (Single Race, Postcard Race and Multiplayer Grand Prix). The tracks have dynamic elements with shortcuts and you can collect boost by drafting or sliding, for additional speed or even a jump.
