Since we can't hear music in the streams I don't know if maybe this is in somewhere. But i've heard many people just always turn off their music in mmos. But this isn't like mmos, and I don't know about yall but Mass Effect, Fallout, and even Xcom (not a shooter but still) would be far less entertaining if you didn't have any kind of combat music.
Would combat music be something yall want to see? Or would you even care? That giant metal looking thing in the co-op trailer I would give a song like this. :)
