Fans around the world eagerly count down the days to the release of "Call of Duty: Black Ops II"

In just a few days, they will also be able to fully immerse themselves in the music of the game with the epic soundtrack. Featuring a brooding theme by Trent Reznor and the original score by Jack Wall, the soundtrack for Activision and Treyarch's hotly-anticipated blockbuster delivers on the emotional intensity of the game.

The music is a reflection of the complex narrative being told by Treyarch, taking players on an audible journey around the world, influenced by the cultures and conflicts that will immerse players in the experience.

"The story surrounding the single player campaign was of paramount importance to the developers at Treyarch," Wall said. "I wanted to do my part to give that story as much emotional depth as I could with the music. I think the fans will really appreciate how deep the story is in Call of Duty: Black Ops II."

Releasing the same day as Treyarch's blockbuster game, the "Call of Duty: Black Ops II" soundtrack, features more than 40 tracks, which will be available online on iTunes and through select digital marketplaces for$11.99. The soundtrack will be included in both the "Call of Duty: Black Ops II Hardened Edition" and "Call of Duty: Black Ops II Care Package Collector's Editions", respectively.

Reznor, known for his composition on the score for "The Social Network", as well as the feature film "The Girl With The Dragon Tattoo" brings his distinctive style to the biggest entertainment property of the year. Wall, one of the well-known and highly-acclaimed composers in the video game industry, composed the emotional score for "Call of Duty: Black Ops II", bringing the visceral title's audio landscape to life.
