Song Name

Hi,
I'm looking for the name of this song. YouTube - Left 4 Dead (26 Achievements Menu) according to the guy that made the video it is by Elucidate, but it is part of a mix which is over an hour long. I know that the Elucidate mixes are just a composition of songs so if anyone can tell me the name of the song it would be much appreciated. I've been looking for almost a year now... =$

Thanks in advance.
