Doom Eternal: Mars Core Master Level Ultra-Nightmare [No Hud]

Mars Core is 1 of 2 new official master levels, this is my first UNM clear. 2 areas that I was mostly scared of here, the section immediately after getting the BFG and the smoke filled room. I think I got myself trapped there at one point in both areas so I was kind of lucky to make it out alive. Had some ammo trouble with the cyber mancs at the very end in my nightmare playthrough, so I decided to just BFG that section once instead of getting myself killed. Enjoy!
