Crappy music
Having a hard time getting into the game so far, please tell me this gets better. I know I've got a ways to go, I just released the Forerunner. But yeah, the music is awful. No tempo to it, doesn't set the mood, doesn't provider a sense of urgency. Hell, I barely even notice its there half the time.
Also, whoever mixed the sound for this is goddamn retard. The Warthog sounds terrible.
