A run through the the Cultist Base Master level at Nightmare difficulty. I die a couple of times near the end, though I had extra lives to spare. This can be insanely difficulty if you don't know how to quickswap weapons and use every bit of your arsenal but also insanely fun. I still need to practice if I want to so deathless run run and I don't think I have the patience or energy to do an Ultra-Nightmare run of the whole campaign. Still I hope you enjoy the video. :) My Twitter:
