Audio Surf is a game that allows you to import your own music into the game and generate race track type things from the music you import. Audio Surf 2 looks to not not only let you ride through your music but also run, jump, and actually surf through your music.
The new game will apparently also support mods allowing users to alter how the game interprets your music.
The game is available on Steam Early Access which means it has not yet been completed, but for a discounted price you can start playing now and help to shape the game’s development.
