I really enjoy completing levels pacifist style, even if I'm not good enough to beat any records yet. I'm getting much better at them than I was, though. I noticed that a few Hell Revealed maps are almost designed to be beaten pacifist style, such as MAP21 and MAP19, so I recorded a few demos that I hope you'll enjoy. They're recorded with Chocolate Doom.

A few comments here:
MAP10: Not much interesting here. I made a few mistakes, and it looks jittery in some places because I was debating whether or not to use SR50 there.
MAP12: Fucking hard. If there's anything that could possibly go wrong in this map, it happened to me when I was trying to beat this map. Cockblocked by an archvile, mowed down by the Spider Mastermind, having the arachnotrons fail to leave their starting area, everything! Then, all of the sudden, there was this one run where pretty much everything went right for me, even the Pain Elementals forgot I existed!
MAP19: One of the easier ones. I really should have 33 seconds on this one, but I lost a couple of seconds. Why? I skipped over not one, but two exit lines!
MAP21: Extremely easy. As long as the imps get cleared out, you're pretty much clear.
MAP27: I actually had a run of this in 1:17, but my computer took a dump while I was copying to a different folder, so it's lost. The hardest part is getting the skull key next to the Cyberdemon. Also, in one run, the archviles bounced me through the window and I ended up going through one of the teleporters, sending me way far in the level (I died after that, though). Could a ridiculously fast time be achieved by doing this on purpose?
I'm planning on doing a MAP14 run next; the furthest I ever got was almost getting out of the yellow key hallway. Also, MAP15 is actually possible if you're the luckiest doomer on earth (or TASing!)
