Microsoft's Kinect Sports is one of the first retail releases for Xbox 360 to use the Kinect hands-free accessory system. Sports-themed mini-games are played through a controller-free interface that can sense motion, detect gestures, and pick up spoken commands. Family room athletes make their in-game personas kick a ball, swing a racket, or run a race by performing the action in front of the Kinect three-dimensional sensor device. The game features whole-body activities based on six sports: beach volleyball, bowling, boxing, table tennis, track and field, and soccer. Games can be played solo, or in competitive or cooperative multiplayer modes.
