Trent Reznor Working on Call of Duty: Black Ops 2 Soundtrack

"It didn't make sense to have a gung ho, patriotic feeling theme song. It has to feel weighty. There is a lot of remorse and apprehension here" said Reznor in an interview with USA Today. "What I learned in listening to the full story and the amount of effort that has gone into the back story and the characters and the full preparation there is a lot of reservation and angst and sense of loss and regret and anger bubbling under the surface. So it didn't make sense to have a gung ho, patriotic feeling theme song. It has to feel weighty. There is a lot of remorse and apprehension here."

This is not Reznor's first foray into making music for videgames. id Software's Quake credits its music to "Trent Reznor and Nine Ince Nails." The NIN logo even appears on nailgun ammunition boxes throughout the game. As a fan of Doom, Rezor also took the helm as sound engineer on Doom 3, though he eventually abandoned the project down the road. His audio work didn't make it into the game's final release.

When asked how he became involved with Call of Duty, Reznor said, "I have always looked to that franchise as the cutting edge of what seemingly unlimited budgets and full-on not cutting any corners can do in the current day and age."

Call of Duty: Black Ops II is due out November 13 on Xbox 360, PS3 and PC.
