Sorry to bring back this thread, although it isn't that old. Not yet.
I have a silly question about this mission: what is this bonus objective Setekh spoke about? I played through the campaign a few times, but I have never seen that canon. I didn't really look for it either, I was busy enough with the front beams.
And to answer the question, two beams down the first time around. (Medium level) After that the four beams are usually down, if I manage to survive that is. Am I the only one who has more problems with the fighter escort than with the Sathanas itself? These fighters are very skilled at ruining the day and preventing me from surviving. They must know that the biggest threat in the universe is neither the Colossus nor their Sathani fleet, but Alpha 1.
Fifteen ships are supposed to deal with the escort wings, but they aren't quite effective. They seem to behave more like unarmed drones than actual fighters or bombers, as they are shot down at an impressive rate. (Less than two minutes of fighting and four wings down. Good luck Alpha One with the Beleth) Sure, they aren't attacking me at least. (A friendly trebuchet killing you right before the end of the mission is *so* frustrating)
