Please note this is the soundtrack score to the videogame Halo 2 for the XBOX system.

With video-game soundtracks developing into a full-fledged genre of their own, the meticulous remixing, compiling, and production on 2004's HALO 2 heralded the trend. Reworked versions of the video game's original theme music by Michael Salvatori and Martin O'Donnell take up the bulk of the album, with an overall sound that owes a debt to contemporary electronica, New Age ambient, 1970s stadium rock, and orchestral music alike. The surging, cinematic vibe of HALO 2 's original score offsets the alternative-rock and metal acts that populate the rest of the set list.
