Soccer/Football is a sporting activity found in Kinect Sports Rivals.
It is played by replicating many of the moves you would make if you were playing an actual game of football. You will need to swing your leg as if kicking the ball in order to pass or shoot and the Kinect sensor will accurately pick up the ball's direction of travel based on your gestures. Similarly, you can use your body to block the ball if defending.
Soccer can be played both in single player, against the AI, or online multiplayer or local multiplayer against a friend.
