So, would it not be absolutely awesome to have a DLC expansion that allowed us to play the Campaign in an “Alternate Soundtrack” mode, which replaced all the music in the game with their Remixes from the limited edition OST?
A few other awesome “Alternate Soundtrack” mode would be one that replaces the music with tracks from the original Halo trilogy. Or one that used tracks from the “Spinoff” trilogy (Wars, ODST, and Reach), and even one that used tracks from the Halo movies, Legends and FuD.
I would love to see this come around in Halo 5 as well, it would be like if the Borderlands easter egg “Extra Wubs” actually did anything.
