Quincy Ruins

The Quincy ruins is a location in the Commonwealth in Fallout 4. It is the sacked city where the Commonwealth Minutemen made their last stand.

Background
The hometown of John Adams, John Quincy Adams and John Hancock, this town was briefly occupied by the Commonwealth Minutemen. However, the town was sieged by the Gunners after Clint, a fellow Minuteman, betrayed his own for a position of leadership. The abandoned town was repurposed as a Gunner fortress, with two distinct sections, including the town itself and the fortifications on the highway.

Layout
Baker will be on the church rooftop wielding a Fat Man. Inside of this unmarked church building is Sturges' terminal, which tells of Mama Murphy predicting an attack on the settlement and the settlers requesting help from the Minutemen, as well as a "couple suits of power armor" - Tessa's suit (the one that "won't start" and had to be dragged there), and the one lying on the overpass' wooden lookout, which Clint tries to reach in case of danger.

The last entry on Sturges' terminal is from a Gunner, stating that a small group escaped the attack and fled under the pursuit of a Gunner lieutenant and his squad; this presumably being the twenty people, including Preston Garvey and his group, whose numbers would diminish by the time of reaching Concord. There is a power armor station and a weapons workbench within the church. Another station is across the street at the Red Rocket to the west.

From the top of the church, one can reach the Gunner camp. The camp rests in the northern part of the ruins, on the freeway overpass. The overlook can be accessed by crossing any of three bridges connecting to the roofs of the adjacent church, the radio tower, and a house. The stronghold hosts several living quarters among the derelict cars, and a collapsed road in the western part leads to the second tier. This tier holds a watchtower and small command station between two trailers. The command center has a terminal and a steamer trunk. There is also a parking garage located in the south of the ruins, which contains two leveled radscorpions burrowed in the ground.

Notable loot

 * Nuka-Cola Quantum - On the lower level of the elevated freeway, in the cooking area west of the church entrance.
 * Mini nuke - On the upper level of the elevated freeway, in the small wooden shack. It should be located under the table with the radio and ammo box.
 * Guns and Bullets - On the upper level of the elevated freeway, next to the terminal. Take the church up and follow the path west to the ramp leading up, then around the other side of the truck right at the ramp.
 * Good Intentions - Unique laser rifle carried by Clint, who will be wearing mixed T-51/T-60 power armor minus the helmet and can be found just past the ramp to the upper level of the elevated freeway. He can occasionally be found out of the armor, mainly at night, at which point it can be stolen. If it cannot be found on Clint, check around the truck and trailer on the lower level of the freeway by the beds. Take the church up and follow the path west to the ramp leading up and the truck and trailer are in front of the ramp.
 * Tessa's Fist - Unique raider right arm power armor, looted from Tessa.
 * Tessa's holotape and an almost complete set of heavy combat armor - Looted from Baker.
 * Fusion core - One on the first floor of the church, in a wooden box next to the terminal; another on the second floor of the police station, in a wooden box on a desk near a cooler and ammo box.
 * Mama Murphy's note - Quincy Apartments, on a dresser on the upper floor in a heavily-furnished room, accessible from both the diner and Guns Guns Guns.
 * Mama Murphy's stash - Quincy Apartments, cooler containing a large number of chems, on the balcony accessible from the room containing Mama Murphy's note.
 * Receiver schematics - In a store, in an Expert-locked safe.
 * Quincy shop key - In a nearby cash register.

Bugs

 * The headless T-45 power armor on the overpass will respawn every time the area respawns, allowing for infinite T-45 power armor suits every time the ruins are cleared of Gunners.
 * The power armor frame and power armor are listed as owned, and will be marked as such if you decide to take them.
 * Some followers, such as Preston Garvey, do not react at all when entering the headless T-45 power armor on the overpass, even if the prompt reads "Steal".
