Really noob question here, so bear with me.
I haven't played Inferno for a while, but as far as I can remember, there was this very difficult mission (one of the last, if not the last one) over planet Earth where you should ambush very big cap ships and stations (you have to take out the beam cannons of the final cap ship so that your cap ship isn't wrecked). I don't think I have ever finished it (never quite got the hang of that level), but I kept playing it just for the sake of the music.
That piece of music is epic. I ask you if you know its name, where is it, where can I listen to it, etc.
