I liked it but as the guy above mentioned you should build it up to a more apocalyptic ending. I mean, it's a theme that projects impending doom in the game and the music is pretty much helped with what is going on with quakes, the bells and the non.stopping clock in the HUD.
You should definilty build increase the tension as it goes along, maybe -if possible- change from synths to a chorous to build up drama. Just a thought.
Maybe for the cherry of the pie you could finish abruptly when you build enough tension and leave some notes hanging from the synth and finally conclude with a xylophone playing the "Oath to Order" as a sign of hope.
