You enter over the first zombie's body, and see the stairs down from before. They're covered in decaying flesh, presumably fallen from the zombies outside. Each wall of the room is mostly covered with a plaque. The left and right are covered in writing, names of the buried, most likely. The far wall, around the stairs, shows a map.

The smell of decay is intense, here, and you can only imagine that it'll get worse down below. You hear movement there as well. Shifting feet, scraped stone, and some sort of squeaking once in a while.

Cave => Crypt, I'll just assume...
