Sonic Free Riders is the third and final entry in the Sonic Riders spin-off series, released as a launch title for the Xbox 360's Kinect peripheral. The game received largely negative reception due to unresponsive motion controls.
The game is also notable for being the first Sonic game to feature a Los Angeles-based voice cast (predating Sonic Colors by twelve days), replacing the New York-based cast from the games prior (excluding Mike Pollock, who kept his role as Dr. Eggman). And until Sonic Racing: CrossWorlds, this was the last Sonic racing game to be developed in-house by Sonic Team.

The game is internally known as SRN, which can be found many times throughout the executable. "SRN" is likely an abbreviation for "Sonic Riders Natal", especially considering that "Natal" was the codename for the Kinect.
