Also, when you get to the bottom of the second downward tunnel, skip the elite in the next room by jumping over the railings. And yeah, engies make that run so much easier with mortars and bombs. That said, good luck, this game likes to tease you by dropping 2 pieces of gear, then never giving you that third piece.
Anyway I dusted off my old assault cruiser, and after playing an oddy for so long it feels weird being able to turn again. I'm actually adding torpedoes to my firing rotation again, so that's good I guess.
