The first Mission to have undead? not true, Bearpits came first. First mission to have an ingame shop? Custom textures? Well technically Gathering at the bar had custom textures. But those were not nearly as visible as the ones here.

The high priests rooms are a bit broken, though I suspect that is a newdark issue. The high priest's dialog is very hard on the ears, and repeats everytime you enter his area, which is also a bit unfortunate.

There are a few secrets hidden around which, while not too well hidden, have levers which are extremily far away from the doors they open.

An impressive effort. Old, and a bit janky, but actually very enjoyable.
