Sonic makes his Kinect debut with a Kinect-exclusive sequel to the previous generation's Sonic Riders . This game, titled Sonic Free Riders , is notable for being one of the few Kinect releases that are part of a pre-existing franchise, alongside most other launch titles that are Kinect-specific "show-off" titles. Sega also claims it as the first title controlled by "full body movements".
Like previous entries in the series, the game is played controlling characters from the Sonic franchise as they race through closed tracks going over jumps, performing stunts, and attacking one another. The difference now is that the controller is removed in place of full body movement for control. The game is for one or two players on a single Xbox 360, or up to eight online. There's even a mode called Tag mode, where two players may work together by placing their hands together and moving in sync to control their characters onscreen. Besides hoverboards, the option to ride bikes has been added to the game.
There is a story mode featuring Sonic and friends versus some bad guys – a bunch of birds from "Team Babylon". Story mode features four teams, each with three characters, along with additional characters. The teams are Team Heroes, Team Babylon, Team Rose, and Team Dark with nineteen total characters, including an Xbox 360 Avatar as an option. Characters are divided up into three classes: Speed, Flight, and Power.
Players can collect rings through the race tracks which can be used to level up characters and enhance various attributes. There are also weapons and other items that use specific motion controls, such as physically throwing a missile or item at another player or character.
Menu navigation can be controlled by voice through the Kinect device.
