MMO Soundtrack

I need a creepy soundtrack designed for an MMO that I am designing. This will be the first of many tracks but will be the key track played in trailers, game opening credits/sign in etc.

I found a track that I love on youtube, but obviously I want originality and own track, check it out to see what kind of thing I am looking for:

The game is a horror/survival MMO for reference :)
