At 70 now. Found the Jackhammer, which I decided to keep, since my supply of bullets is steadily shrinking. Found the Jackal earlier, but wasn't impressed enough to keep it. Found a hell of a lot of uniques/exotics, which you'll likely see when I'm posting the mortem for this one (regardless of if I'm going to make it). Found the Jackal earlier, but wasn't impressed enough to keep it.
So far, however, I've assembled the Storm Bolter, Energy Pistol, Focused Double Shotgun, Assault Rifle, Tactical RL, Fireshield (found the Onyx in the first level I played after my previous post), Hyperblaster, Cerberus Armor and Cerberus Boots.
I'm going back in again; I want to finish this before dinner :)
