Dunwich Borers is a location in the Commonwealth in 2287 and is home to a group of raiders. After clearing out the raiders that occupy the above ground portion of the quarry, the Sole Survivor can enter an underground section.


Before the Great War, the site was owned by Dunwich Borers LLC, a company that manufactured rock drills for tunneling and drilling.

Initially, from what can be read from terminals, the work site was extremely hazardous and a general lack of employee safety was apparent. However, as the Sole Survivor progresses further through the underground mine, a sinister operation is partially revealed.

It is never exactly revealed what the goal of "Management" is, although a flashback vision and the ruined shrine at the deepest part of the mine, coupled with the consistent negative effect on the people who have taken up residency here points to dark supernatural forces at work. It is possibly related to the ritual that was performed in the Dunwich Building during Fallout 3, where the supernatural entity called "Ug-Qualtoth" was being honored.



The entrance is located at the bottom of the quarry. The area is guarded by about a dozen raiders, including one in power armor.

There is a tripwire trap not far from the entrance. Upon entering, on the left there is a lift which leads to a door requiring a key from the corpse on the other side of this door where the Sole Survivor will emerge after going all the way through the facility.

Continuing ahead from the entrance, is a turret and several more raiders. A circuit breaker switch controls the power and some of the spotlights. The unlocked Station 1 terminal is next to it on the right and can be used to turn off turrets, but be wary as there is a grenade trap near the terminal. Ahead of this, there is a small camp with a machinegun turret, a mattress and a cooking station.

The way ahead now leads to the left. A side ladder leads to a (Novice) locked cell (tripwire trap at the bottom of the stairs), and back down the main path is terminal 2. Just beyond the terminal is a weapons workbench with an ammo crate, a sleeping bag and a (Novice) locked cooler. Continuing on to terminal 3, a huge pit opens up at the bottom of which Bedlam will be found.

A (Novice) locked terminal belonging to Bedlam is attached to the reservoir in the middle of the pit. There are also an armor workbench with an issue of Astoundingly Awesome Tales placed on it, a steamer trunk and two sleeping bags. Ahead from the pit is a door which Bedlam has apparently chained shut; removing the chains allows access to a corridor with feral ghoul corpses. Farther along, near a wrecked machine with a skeleton, is a door on the left. Opening it triggers the first flashback.

There are more circuit breakers in the ghoul infested area; activating them turns on the lights and triggers a large group of ghouls to start running towards the player character.

Once past the initial ghoul attack, there is a significant fork in the path. Straight ahead is the way to work station 4 and beyond it a water-filled pit with another flashback. The left hand part of the fork heading upwards leads to work stations 5 and 6 and eventually back to the exit.

Dunwich Borers only appears in Fallout 4.


如同3代的丹維奇大廈,裡面出現的超自然現象連結自戰前在該地發生的事件,這參照了小說家H.P.洛夫克拉夫特及其作品克蘇魯的呼喚內章節:丹維奇恐怖事件。Note that in the bottom of the well in the end, one can see part of a statue that resembles a face. Using console commands it's possible to clip outside of the map to reveal the whole statue. The buried statue might be a reference to another one of Lovecraft's stories, The Shunned House, in which the protagonist digs underneath an abandoned, haunted house, only to uncover the elbow of a colossal being buried underneath.
