Doom 2 - Map 20 (Gotcha!) - Nightmare (Solo Co-op)

One of the harder ones for me. Let's not talk about me fumbling the jump near the pain elemental twice - normally I am able to kill him without issue.
I was very lucky at the rush to the end I'll admit. It was the first time getting that far and making it to the exit with 1 health is the ultimate clutch.
