Ride your music.
Audiosurf is a music-adapting puzzle racer where you use your own music to create your own experience. The shape, the speed, and the mood of each ride is determined by the song you choose. You earn points for clustering together blocks of the same color on the highway, and compete with others on the internet for the high score on your favorite songs.
Audiosurf on Steam includes The Orange Box soundtrack, integrated with the game to enable "Still Alive" surfing and more. In addition, Audiosurf is one of the first titles to leverage the recently announced Steamworks, offering full support for the Steam Achievements that appear on Steam Community profile pages.
