Konami Digital Entertainment and Microsoft have announced that Rhythm Party, an all-new dance title for Xbox 360, is now available via Xbox LIVE Arcade, priced 800 MS Points. The key to Rhythm Party is a total freedom of movement in front of the Kinect motion sensor peripheral. The new game offers 'open format'dancing so, unlike other music and dancing games, does not rely on contrived choreography. Instead, as the player's silhouette is shown on screen, players can move to the beat and groove freely to create their own performance. These dances are rated as they coincide with performance 'ripples' on screen, with points and bonuses awarded that bolster the player's score.
