Help finding a factory map?

[zodiac]

I'm looking for a wad I played once, but I can't remember the name for the life of me! It was a dark industrial map where you approach a factory through some slums, then press through it.

I remember that it was really detailed, especially the back of the factory which had raised catwalks and cacodemons. The place was riddled with passages, and there was a mastermind inside. Does anyone know the map I'm talking about?

Map 13 of Fragport springs to mind, though it's not exactly "riddled with passages" and the spider's outside.

Sounds a lot like a map in Roger Ritenour's Phobos:

Valhalla? Dark, detailed and had cacodemons.
