These adapters were bundled with the Kinect itself, but are not included in Xbox 360 system bundles containing the Kinect. The original Xbox 360 requires an additional adapter containing a USB connector and an AC adapter, as the system’s USB ports by themselves do not supply enough power to run the Kinect. The Xbox 360 S and E models have a dedicated Kinect port on the back of their respective units. The Kinect for the Xbox 360 is currently incompatible with the Xbox One. Sonic Free Riders was released exclusively for the Kinect and so far it is the only Sonic game to use full functionality of the Kinect. Kinect was released to compete with the Wii Remote's motion controls and the PlayStation Move for the PlayStation 3. Kinect is a motion sensor camera created by Microsoft for the Xbox 360 and was released in late 2010.
