Quake Scourge of Armagon E2M4

No-commentary playthrough of Quake - Scourge of Armagon expansion on Nightmare difficulty. I think I must have played this at some point because a few things were familiar, but I don't remember the majority of any of it. This version of Quake is at https://store.steampowered.com/app/23... - I'm not trying to sell it, and I don't get any money if anyone buys it. I'm just sharing it in case anyone cares.
