Quake Dimension of the Machine E5M2 on Nightmare

No-commentary playthrough of Quake Dimension of the Machine on Nightmare difficulty. This is E5M2 - Too Deep, Too Greedy. I haven't played this expansion before, but it seems to sort of share a level structure with Dawn of the Machine released recently. In Dawn of the Machine, however, you have to revisit levels after getting runes to find more runes hidden within the level, whereas in Dimension of the Machine you have to get the rune in the second level of each mini-episode in order to finish the level. 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.
