Pitt Steelyard

The Steelyard is a location which is added to Fallout 3 in the add-on The Pitt. Upon entering the Steelyard you will find a dead slave with two Steel ingots. This also is the location for the achievement/trophy Mill Worker for finding 100 ingots.

Noteworthy sites

 * Slightly northeast inside the Steelyard there's an old Supply Plant which contains the Man Opener and 18 ingots.
 * On a staircase to the southwest, the player can find the corpse of Wild Bill. His corpse contains a note to Milly, which is used to finish the unmarked quest Wild Bill's Last Stand, and his unique gun, Wild Bill's sidearm.
 * Due east of Wild Bill, at the end of a stretch of downward-sloping grating, there's a Wildman with Gamma shield armor, a head wrap, a worn slave outfit, assault rifle, and a couple of boxes of ammunition. There are also several ingots.
 * At the north end of the train tracks, there is an entrance to the Pitt Underground which can be opened with the Power Plant Key.
 * In a closet inside the Supply Plant, there is a terminal with diary logs, detailing a shift from human workers in the factory to Protectrons. The diary logs explain the three skeletons found just outside the closet door.

Bugs

 * Sometimes, the area leading to the top of the blast furnace will be non-clip (untouchable) and impossible to climb. It may possibly occur on its own, but is more frequently associated with Xbox 360 consoles with the Point Lookout add-on loaded. Restarting the console may occasionally clear this problem (you may also need to load a save inside the Steelyard after the restart, as the building seems to be set as noclip whenever you enter the area).
 * A rare bug is when you fall into a blackhole on one of the roof above Wenher's Hideout and fall to your death. A Wildman can be seen on the opposite side of the roof. (If you land on top of Wernher's Hideout, you slowly land on other objects and get out of the map) restarting your Xbox may work (It happened again after a while and fixed it self after reloading a save) while reloading a save and dying will not.
 * The wall by Wild Bill can become non-clip. This makes it easy to fall through if you don't realize it has happened. It is possible to get back into the map by doing quite a bit of climbing and making your way towards the dead slave with the Auto Axe, but it is very difficult. If you do attempt this, be warned that if you approach the slave from outside the fence, the Trogs may glitch under it and attack you. It is interesting to note that you can see the bottom of the reactor tower and the skeletons of the others that have fallen into it.
 * A known bug for this quest is that if you don't find Wild Bill the FIRST time you enter the Steelyard he will be lost forever. This makes it impossible to get his unique weapon Wild Bill's sidearm, and his note explaining his fate to give to Milly for quest completion and reward. If his body doesn't appear the first time, re-loading the save at the Steelyard entrance should make him spawn in a reachable location.
