Supply plant

The  is a place in the Fallout 3 DLC The Pitt, accessed from the Steelyard.

Inside the plant, the player can find several Steel Ingots as well as uncover a small side story about the fate of its workers.

Inhabitants
A pair of Wildmen can be found in the second room of the Supply Plant, just past the main entrance. The rest of the Supply Plant is occupied by several Trogs. There is also a Factory Protectron inside a repair chamber that can be activated by hacking a nearby average terminal. The Protectron is friendly towards the player, and helps assist in clearing the plant area of Trogs.

History
The plant's pre-war management began to replace the workers with Protectrons, initially claiming the robots would only be used for plant security. When the workers were laid off en mass despite the supervisor Tom McMullin's stalling efforts, they revolted and attempted to chase after their supervisor who they mistakenly believed to be at fault. McMullin, suspecting this as soon as he heard the management order, tried to escape but was chased into a small room where he locked himself in. When the new Protectron work force arrived, the robots proceeded to kill the human workers. Alarmed by the noise, the supervisor left his room but went back soon after, shocked by what he had witnessed, planning not to leave the room again. As a skeleton is found in the room where the terminal with McMullin's accounts of the event are located it can be assumed he died in there.

Notable loot
Note: in the 8 Steel Ingots' stash location, i.e. a dead end with three Wildmen with Flamers filled with trog gibs and mining carts, it's suggested to pay particular attention if using laser or plasma weapons. The editor experimented the irritating experience of having an Ash Pile "created" exactly on the Ingot stash, thus making the Ingots IMPOSSIBLE to pick up: it would be better to use explosives or ordinary weapons to avoid any kind of problem with this issue again.
