Dance Evolution (known as DanceMasters in North America) is a dancing video game developed by the makers of the Dance Dance Revolution series. The game was officially unveiled at Konami's E3 2010 press conference, exclusively for Xbox 360 Kinect. Dance Evolution has 30 tracks, including hip hop, R&B, pop, eurobeat and dance, and will be supported with additional songs as downloadable content.
Gameplay requires the player to copy the on-screen character's dance while hitting certain spots with their hands, drawing lines in the air, stepping on the beat and striking poses (much like a full-body version of Elite Beat Agents). Only hitting the on-screen markers counts toward your grade (unlike Dance Central, which demands full-body move matching). There is a lesson mode that explains the basic mechanics and the main dance mode. Offline games support 2 players simultaneously and online modes support up to 4 players.
