Music of Halo Online

The Halo Online soundtrack is the collection of music composed for the cancelled Halo Online. The soundtrack was composed by Tom Salta, composer of a number of other soundtracks including those of Halo: Spartan Assault, Halo: Spartan Strike, Halo: The Fall of Reach and the remastered soundtracks for Halo: Combat Evolved Anniversary and Halo 2: Anniversary. Due to the game's cancellation, the soundtrack was never officially released, and the music that exists is only viewable via files extracted from the game's testing builds.
