Harmonix is best known for rhythm-focused series like Rock Band and Dance Central, but its next release is quite a bit different — a multiplayer first person shooter. Called Chroma, the sci-fi PC game has you squaring off against opponents like in any other multiplayer FPS, but the key difference is its focus on music. Its a very different headspace than most shooters, Harmonix CEO Alex Rigopulos told Polygon, and on some level much more about creation than destruction. Levels will change at important musical moments, and youll be able to choose your weapons based on sounds.
