Motion Explosion! is a collection of 12 mini-games that require the Kinect peripheral to play. They also use the player's avatar to represent the character. All games can be played alone or for up to four local players, taking turns. The games can be played individually in Freeplay or as Motion Mix, where three are selected randomly. By playing well in Motion Mix points can be earned to level up. In Freeplay stars need to be earned to open up new levels. Each game comes with two Easy levels and by earning stars Medium (level 3 to 7) and eventually Hard (level 7 to 10) are unlocked. Games also often have multipliers.
Gameplay is varied across the different mini-games, but most involve movement and timing. In games like Balance Beam and Heavily Armed, players need to balance objects on a bar or match shapes in a sequence. Other games like Dodge Ball and Juggle Struggle require quick reflexes to dodge obstacles or juggle multiple items. The Kinect peripheral is used extensively throughout the games, adding an element of immersion and interactivity.
Motion Explosion was released on Xbox 360 in November 2011 for players looking for a fun and challenging experience with their friends or family.
