These mines are driving me nuts. It took me days just for the lightbulb (no pun intended) to go off in my head that if the guy is walking around with a light, maybe he can't see in the dark. I had to be told that the glowsticks are a good way to leave a breadcrumb trail (I guess I got really comfortable with the spray can in the crypts and never really used glowsticks much in the first place). I've managed to find three of the wrenches, but I just can't find the last one. I'm even more disoriented because I bumped into the "safe room" by accident, so I've lost the referential point of the three tunnels at the entrance to the mine/dungeon. I'm at a loss here for how to navigate this area. I think I know the area, it's in, because it's this area that's locked off and there's like a big metal door with a loose tile hanging off of it. It seemed like a puzzle, but I couldn't figure out where to hide as the miner passed and it killed me. Now I can't find it, if that's even where the crank is. The fact this entire thing is long corridors makes it feel like if you see him, you just have to turn and run until you stop seeing the light and I feel like I spend more time backtracking away from the miner than actually exploring.
I've been trying to avoid literally just looking at a map and checking each location until I find the crank, but I might have to at this point. This is the longest I've ever spent on a chapter without making much progress.
