Harmonix is working on an Xbox 360 and Xbox One title called Fantasia: Music Evolved.
The game, due out in 2014, “transports players to a breathtaking world where music and magic combine to transform extraordinary interactive landscapes in entirely new and creative ways” according to the press release.
It is controller-free and includes music from the likes of Bruno Mars and Queen. Players will be able to remix songs on the fly as well as access preset remixes made specifically for the game.
