Saugus Ironworks

The Saugus Ironworks is a location in the Commonwealth in Fallout 4.

Layout
The location is a large ironworks factory, consisting of multiple levels. The building contains many vats of molten metal, which both emit light and deal massive damage to players not wearing power armor. The factory consists of metal floors and platforms.

On the middle level there is a room containing both a weapon and an armor workbench. There is also a terminal nearby which can be used to activate a nearby protectron that will engage the forged in combat. On the top level, behind a machinegun turret, there is a door to the furnace in which Jake, the farmer's son, and Slag, a mini-boss, 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 boss fight is locked with an expert lock. There are multiple forged and Frag mines on the roof. Engaging these forged in combat may attract the Gunners on the nearby overpass. One of those gunners, Bridget, may lob mini nukes into the fray.

Notable loot

 * Explosives bobblehead - Found in the blast furnace room on top of the control panel above the furnace.
 * Picket Fences issue #3 - Found in the blast furnace room, on the floor of the steel walkway right under the steamer trunk and the ammo box.
 * A Shishkebab - Looted from the power-armored and Forged leader Slag, who resides in the blast furnace room, needed for the quest Out of the Fire.
 * Dampening coil - In the southeast corner of the blast furnace room. Follow the catwalk to the right and downwards; found on the wall adjacent to the smelter. Needed for the quest Here There Be Monsters.
 * An overdue book and a Day Tripper - Near the stairs in the southwest corner along the west wall on the ground level, located in the toppled smelting pot next to a skeleton and shopping basket that is found directly down the short stairs adjacent to the gun-trapped bathroom.
 * A Vault-Tec lunchbox - On the top floor of first room. It is located just north of the far south wall, in an office nook.
 * Saugus roof key - on Slag, Jake Finch and a Forged leader. Opens roof door.

Behind the scenes

 * Saugus Ironworks is a counterpart to the real Saugus Iron Works National Historic Site.
 * 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, character became 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.
 * The Explosives Bobblehead might not spawn.
 * 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.
 * Game occasionally freezes when moving inside the Saugus Ironworks interior.
 * Upon leaving the Blast Furnace room when detected ([Danger]), all items and enemies will respawn and all containers will refill.
