Quake Dimension of the Past M5 on Nightmare

No-commentary playthrough of Dimension of the Past for Quake on Nightmare difficulty, this is M5 - The Stronghold. It is the fifth episode of the game after the base four episodes, released by MachineGames to celebrate the 20th anniversary of Quake from what I have read. I don't know if I've played it before, to be honest. 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.
