This one was pretty challenging for me, and I guess I missed a good portion of the enemies in it. Watch me play it here: Acerbus - The Quake Grave

Yeah, I missed more than half the monsters as well for some reason... maybe somewhere in a secret you're barraged with them. Anyway, of what I played it was a very good level. I liked the interconnectivity of it. The visuals were decent. The fights were pretty good as well. The one thing I didn't like was the ridiculous crusher traps, those were just annoying. Worth a play, though.

Unfair traps, poor health/ammo balance and uninspired architecture combine to make this map rather uninteresting and disappointing to play.

I have to admit, I found the map more enjoyable up until the point where I passed the silver key door. The reason can be seen in ArrrCee's video as well, as he encounters the same issue I did. Still, large, boxy rooms and strange enemy placement make this a rather low-quality release in my eyes.

This map is weird and, despite a few interesting ideas, not very fun. As previous commenters wrote, the crusher trap and arbitrary enemy placement are frustrating. The secrets are frustrating too: one includes a death trap, another can't be reached without running across a lava pool, and a couple require shooting random sections of the wall/ceiling, including one that can't be reached without walking along the top edge of the map.

I got 62/81 kills. There are a ton of rotfish under the walkway that leads to the room with the gold key. It's easy to knock most of them out by lobbing a grenade down at them. I have no idea how to get to full kills.
