I need assistance Identifying a song from a game.

I was looking through my computer for sound clips for the new Windows Live Messenger, and found a file called Maintheme.wav, the song sounds so familiar but I cannot place what game its from.....

I uploaded it to my site, it has a tendency to be slow sometimes(less than 100kB/s) so excuse me if its slow.
I downloaded the initial copy(wav 17mb in about 30-45secs)
www.cglz.us/Files/Maintheme.mp3

In my defense I play so many its hard to remember.

There was one slightly similar theme in Unreal Tournament 2004.

Ok, I'm an idiot.....I just did a quick google search which I should have done in the first place, but its Frontlines Fuel of War.

It was at the bottom of the first page.....I assume I downloaded it back when I was still actively playing the game.

I appreciate the help though, And Stemnin and Morton you were both close, it uses UE3.

Matthew Harwood was the sound director for the game, I think I grabbed it a while ago when he mentioned in the Kaos forums it was available to download
