Acclaim announces that open beta testing of DANCE Online is underway, allowing the chance to sample the virtual dancing of this dancing with the nerds MMOG. Here's word on the game, which will remain free to play even after beta testing concludes:

Players of DANCE! Online can create their own avatar and use either the keyboard or most PC compatible dance pads to match the beat of the song and to make their character perform choreographed dance steps. The game features up to 6 players dancing together and includes a variety of game modes and options. Players will be able to purchase optional items from the game shop to customize their virtual characters with clothing and various accessories. Players can also purchase “song packs” to dance to even more songs from WMG’s catalog. The game is free and will be supported by in-game advertising provided by IGA Worldwide.

DANCE! Online is directed by video game industry veteran David Perry. The game is in Beta testing beginning this week, which means that anyone who registers for an account can immediately play for free. For more information, please visit www.acclaim.com.
