This map is definitely a little annoying to speedrun. The opening feels extremely RNG to hit the mancubus, but I found having the crosshair on helps a lot. When raising stairs sometimes enemies will get raised up with them blocking your way which can ruin a run. Final elevator is also very difficult to do fast and without taking too much damage. Sometimes the spider at top of the final elevator dies saving you a couple extra rocket shots.

This run was one of my best openings I had with the mancubus but it could still be a lot faster. Was very glad I got by the revenant that got raised with the stairs. I also get really lucky at the end elevator not having to deal with the spider.
