I must admit the music is epic and while I loved the beta at points it did feel like the music over hyped the situation a couple of dregs are shooting at you?......CUE THE EPIC MUSIC!....oh you've already killed them......
One moment where the music was spot on was the last story mission in old Russia (turning in the array) have hive tomb ships boom (DC comics reference) in and dish out its contents with the music playing have me chills (solo'd my missions as my mates weren't on :( )
