A guide specifically for making your Impossible Mode as easy as possible. I forgot to mention in the video is the reason you want to do this method at this specific point in the story is because Necromorphs don't seem to spawn randomly, but only during this part. Your main objective should be rerouting power from mining administration and you want it to stay there for the entirety of your pulse round method. It takes 192 nodes to fully upgrade all of your weapons and suit. It would be around 1,920,000 credits if you were to buy all your nodes for your upgrades.
