Big map with a lot of tough monsters. There's a decent amount of ammo and the rooms are very large, so there's plenty of room to dodge and incite infighting. The difficulty is mostly fair, although by the end there's so many Shamblers it's a bit ridiculous. You will want to use rockets a lot to save your shells & nails for them. And one of the Shamblers was floating in mid-air for some reason and sniping me, which was frustrating. But overall pretty solid level.

I really enjoyed this. The layout is complex and multi-story, the atmosphere is eerie in the manner of E4, and the combat is intense. Be sure to conserve your ammo, and keep an eye out for secrets: you'll need them. There are a few unmarked secrets in addition to the two official ones.
