I like the idea of sacrificing an ally to give life to an automaton. It kind of reminds me of the Carcosa setting by Geoffery McKinney.

On that note...
The Factory
A tribe of cargo-cultists inhabits an ancient factory and worships a broken computer in the control room. You must fight insane humans and malfunctioning robots in a industrial dungeon filled with conveyor belts, exposed wires, and leaking reactor cores.
There's a furnace where you can smelt metal items into ingots. You can place ingots on pedestals to make armor pieces and replacement parts appear in their place. Replacement parts are used to get machines working in other parts of the dungeon.
Some things are really heavy, and you don't want to be over-encumbered when you are dodging traps and running through timing puzzles. If you can get the machines working, you may be able to move items around the dungeon by placing them on the conveyor belts.
There's a control room some place in the dungeon. The savages that live here have turned it into a crude shrine where they make human sacrifices to appease their mechanical god. If you can clear out the cultists and get the machine working, you can open up a panel of switches to control the machinery in the previous areas.
