(Fighting the actual boss fight). A Tek suit and shot gun can do this boss fight fairly easy. You could use the federation Tek suit from Gen 2, stay high or far enough away from the boss and you should be fine (if you do get hit you will be one shotted, I got hit with the normal primitive Tek suit and it one shot all the armor). The little drones don't do that much damage, and if you use a catus broth it helps a ton with those. Need a +200 shotgun just like with the brood mother and Rockwell with +500 ammo to be safe. It is VERY cold down there bring soups, MED BREWS, otter, or whatever for the cold. Using the shotgun I highly recommend the shadow steak to shoot farther and recoil ( yes shotgun does shoot farther with it I have tested it). Tek suit I didn't even use 100 element. I did it with two or three other people to do it faster. Just know you lose all the elements that you take with you after the fight because you are thrown into upload afterwards. Good luck. You can't fly your Tek suit through the entrance cave use a desmodus and cryo it when you get through the nasty part.
