Aliens vs Predator game(2010)- Marine trailer music

The part I would like starts at :53. I’d assume it is one piece throughout the trailer but I really have no idea. I can’t find this piece anywhere. Thanks for any help. It sort of sounds like the piece in the Aliens trailer but slightly refined.

Zen444 just posted his rip of the PC Demo and (in thankful thought of his work) I downloaded it. When it was finished and I listened to it ,it seemed to me that it was comprised of parts from the music, which…combined, got the music from the different trailers and stuff.
So I know which one you mean, and it was used also in the Heritage Trailer.
Hope you like it:
