Saugus Ironworks

Saugus Ironworks is a location in the Commonwealth occupied by the Forged in 2287.

Background
Once a historic pre–Revolutionary War ironworks, Saugus was reopened during the Sino-American War. The location is now run by Slag and his group, the Forged.

Layout
The location is a large multi-level ironworks factory, consisting of the main factory and a few smaller buildings on the roof and at ground level. The factory interior consists of metal floors and platforms and contains many vats of molten metal, which both emit light and deal massive damage to player characters not wearing power armor.

On the middle level, there is a room containing both a weapons workbench and an armor workbench, A terminal nearby can be used to activate a protectron that will engage the Forged in combat. On the top level behind an automated turret, there is a door to the blast furnace in which Jake Finch, Abraham's son, and Slag, are found. Opposite that door is a power armor station and a door to the roof.

A shortcut to the furnace area can be taken by walking up a steep pipe on the southern exterior of the building and entering through the door on the roof. The entrance to the blast furnace is locked with an Expert lock. There are multiple Forged and fragmentation mines on the roof. Engaging these Forged in combat may attract the Gunners on the nearby overpass. One of those Gunners, a captain named Bridget, may lob mini nukes into the fray.

Behind the scenes

 * Saugus Ironworks is based on the real world location of Saugus Iron Works National Historic Site, located northeast of downtown Boston in Saugus, Massachusetts.


 * The terminal in the second section contains a list of people punished including a raider called "Yancey" who refused to change his name. This is a reference to the Futurama episode "The Luck of the Fryrish" in which Fry's brother Yancy was jealous of Fry's name.

Bugs

 * After the battle with Slag, the player character can become covered in bright orange molten metal during conversations and in third person view. An easy fix is to reload a save and get lit on fire again by the Forged, turning you back to normal.
 * Surviving an encounter with a container of molten metal may cause the game to equip your character with a permanent, unnamed gore item intended for NPCs killed in this fashion. Because the molten metal is intended to be a definitive death, the game immediately flags your character as dead and equips them with this default "molten death" appearance regardless of whether you survive or not. Essentially, you have a "death mesh" inside your character mesh which clips through in 3rd person view and obstructs the center of the screen when activating sneak mode. This can be solved via the console by using.
 * A pair of raiders seem to spawn quite frequently near the bonfire outside Saugus Ironworks. They will occasionally wander into the bonfire and die.
 * If you exit the blast furnace during the boss fight with Slag, using explosives on Slag might cause his body to become stuck inside the metal cage on either side of the door going into the blast furnace. This means that you won't be able to loot Slag for his power armor or the Shishkebab.
