Halo: Original Soundtrack
Halo: Original Soundtrack is the soundtrack for the video game Halo: Combat Evolved. Composed by Martin O'Donnell and Michael Salvatori, it was released on June 11, 2002. It contains most of the music from Halo: Combat Evolved, with some pieces remixed into medley form. The soundtrack features a wide range of musical styles including chanting, string orchestra, and percussion. A special edition of the soundtrack was released on October 28, 2003, featuring a trailer, demo movie, and music for Halo 2.
An extra DVD was included with some copies of the soundtrack and had four options in the menu:
The second option shows a concept version of the city of Mombasa in Kenya on Earth. It shows appearances from John-117, SgtMaj. Avery Johnson, UNSC Marine Infantrymen, UNSC Marine Shock Troopers , SSgt Marcus Banks and Cortana's voice was heard in the demo.
The bonus DVD premiers the new M12G1 Warthog LAAV, Type-29 Shadow, and Type-52 "Phantom" Troop Carrier. It showed appearances of Brutes, as well as the first versions of the BR55 Battle Rifle and M7 SMG.
X02 Trailer music
The third option is the X02 Trailer Music that shows a image of the Master Chief in the background holding a Battle Rifle about to leave the Orbital Defense Platform Cairo into space. It plays Halo, a song that can be seen on disc of the soundtrack.
E3 2003 Trailer music
The last option is the E3 Demo Music which like the third option shows a image of the Chief but he is dual-wielding SMG's looking up at the sky before Orbital Insertion Pods land near him. It plays The Maw, also from disk one of the soundtrack.
