I think it's Half-Life related, but I listened to the entire sound track of Half-Life 1 and 2 and couldn't find it. I could find similar tracks, but nothing similar to this.

I've tried only music databases, but no luck. It's right on the tip of my tongue almost, but I can't place where it's from. This is actually a track that is in the background
of a mod called Crack-Life: Campaign Mode, which I would advise against investigating unless you already know what it is. I am confident it's not an original track, as it
doesn't fit with the theme of any of the original content in the mod.
