Doom Eternal 100% Ultra Nightmare Speedrun Explained (Old Route)

I play through Doom Eternal 100% Nightmare route, while talking through the various tech we use in the run. I probably left out some details, but that's to be expected. If you have any questions, please let me know in the comments below! I hope y'all are able to learn from this, and I hope to get into a marathon using this video :) Also, I forgot to get the Revanant Shoulder Removal challenge in Arc Complex, but that doesn't change the route much. I just didn't shoot a couple of turrets as much as I should have. (Also a revanant that I normally complete the challenge on didn't spawn, Cause Doom) I stream live on twitch, btw.
