From Konami: Duet mode lets aspiring pop stars play as a team and sing for high scores to classic karaoke duet tunes such as "Under Pressure," "Love Shack" and "Ain't No Mountain High Enough." Players can even practice their separate parts and learn how to harmonize with each other to achieve the perfect score. For some friendly competition, two players can square off and take turns singing every other phrase in a song while joining together during the chorus in Sing-Off mode. The player with the most points at the end of the track wins. Knockout mode offers the fiercest karaoke battle yet, pitting players against each other while singing the same song in unison.
