Awesome...
This would be PERFECT for a fast paced spy type game; kinda feels like a cross between metal gear solid, splinter cell, and the facility theme from goldeneye. Great job!
Also, it's the only one of your songs that doesn't seem to overstay its welcome by repeating over and over, well worth the four plus minutes.
If I ever made a sneaky action game, I'd use this.
