I guess you just skipped this mission, then.
Hahaha......I completely hated that level, but not so much the jumping, I have this thing about heights.
Even in video games.
Classic is the bridge in Half-Life 2, literally makes me nauseous.
But, yeah that level was a little maddening, but all it required was mastering the double jump.
Took me about 2 tries and I suck at that stuff.
No monkey bars, no moving platforms, no closing doors, no walls to grab.................
I wish I had realized it was the future of Doom games.
