Martin O'Donnell, the composer of the Halo score to date, has been replaced with Neil Davidge, whose previous work includes collaborating with Massive Attack, and Matt Dunkley, who has worked on the score of such films as The Dark Knight and Inception.
Both of them hold Martin O'Donnell's work in high regard, but feel it's time for a change of direction:
"Personally, I've loved those games and I've spent a lot of time with them, and gone through each several times. I enjoy them. They can't be bettered, as far as I'm concerned. I didn't sign on to this to improve on what Bungie and Marty have done, but just to take it somewhere else," Davidge told Edge.
"Hopefully the Halo fans will see that we're being respectful, but we've also taken it somewhere else, and maybe onto a higher plane," Dunkley added.
