I was just amazed.
There was this certain aura of intensity throughout this song...and it didn't feel like dragging on either. Of course volume and a lack of bass are the primary concerns. I played the game before listening to this stand alone, so I can only think about speeding down 240 running over zombies, being shot at by a gazillion infantry and having explosions hurl at me when I listen to this song...so I am not suprised.
