Mass Bay Medical Center

The Mass Bay Medical Center is a location in the Commonwealth in Fallout 4.

Background
According to a holotape made by one of the nurses of the hospital, the Mass Bay medical center survived the initial nuclear attack that devastated the Greater Boston area. According to the same holotape, the medical center was then commandeered by the military and continued to treat patients for some time. The situation quickly deteriorated and the medical staff could do nothing but try to make the patients comfortable.

Layout
The layout for Mass Bay is mostly vertical, except for the first floor which is broken into two sections and the second floor which spans multiple hospital departments.

First Floor
The main entrance opens into a 2-story lobby; the Sole Survivor will be facing east upon entering. To the south is a police protectron and the expert terminal that controls it sits behind the nearby desk. East of the lobby are some broken elevators to the north and restrooms to the south. Further east are a kitchen and a fortified cafeteria with a cooking station and a gunner who may be doing push-ups if one sneaks up on him. To the south of this area is another entrance into the medical center. Back to the lobby, to the north is a set of stairs leading to the second floor, but is blocked beyond that.

The other part of the first floor consists of the emergency room entrances and lobby. The main emergency room entrance is to the west, and another entrance can be found across the room to the east. To the south is another broken elevator which houses a turret. Near the elevator is a staircase leading to the second floor.

Second Floor
Starting from the main entrance staircase, to the south is likely an Assaultron on patrol and also possibly a leveled gunner who patrols the area. From this main area there are paths to the east, southeast and south. Heading south takes one to the emergency side of the hospital, including the staircase down to the first floor to the west and exam rooms to the east. Heading east one encounters another small lobby and multiple exam rooms, one of which has a chemistry station. Further to the east is a medic protectron controlled by a novice terminal right next to it. There are two locked exam rooms - one is expert-locked and contains a gruesome scene, the other is novice-locked and has an addictol.

Back to the main area, the eastern path closest to the staircase leads down a hallway which curves to the south. Beware, around the corner lies another turret protecting yet another entrance into the medical center. This entrance is reached by taking the wooden stairs that circle the building on the outside.

Main area - the southeastern path leads into a room with two cells, one of which contains a dead minuteman. Behind the nearby desk is a novice terminal which can open the novice locked safe just below. Continuing on leads one into a room where the third floor has collapsed, creating a path up. It also contains several curtained-beds which contain various things like a chemistry station and ammo.

Third Floor
Going up the collapsed floor path leads to some rooms - two lab-type rooms and a small office. Beyond this is another reception area with two broken elevators and the creepy baby in a carriage. The staircase that was blocked from the second floor is now clear and can be used to reach the fourth floor.

Fourth Floor
Yet another reception area. Here there are doors leading to a new area, Medical Center Station North, and a working elevator. Take the elevator to continue.

Seventh Floor
The elevator opens up to the seventh floor. The floor goes to the right of the elevator, or east, and opens up into a three-story atrium. Be prepared, there is a gunner commander on the eighth floor directly east who will try to enter a suit of power armor just north of him if one is detected. There is also likely another gunner on the ninth floor. Various collapsed floors create ramps leading to the next story in the building. Take seven to eight, then to nine.

Eighth Floor
There is one thing of interest on this floor - power armor. If you're lucky you can take the whole frame, which is a T-45 missing the helmet. There also happen to be two power armor stations.

Ninth Floor
To the west on this floor are some more cells. One contains a dead Brotherhood of Steel scribe. To the east is a room with a collapsed ceiling heading up or a hallway leading further back. If one heads back, one will find an MRI machine and some offices, one of which contains a novice safe. When done with the area, take the collapsed ceiling to the tenth floor.

Tenth Floor
Not much of note on this floor, other than the elevator leading to the roof.

Roof
On the roof is a small living area with various junk items and drugs, and a u-turn from the elevator leads to a MILA drop point. There is also a window cleaning elevator that leads to the Ticker Tape Lounge. One can also see the vertibird that crashed into the building, which created a path to the other roof with nothing of interest.

Notable loot

 * Flamer fuel and a flamer behind an expertly locked door on the 2nd floor.
 * Addictol in a room behind a novice-level locked door on the 2nd floor.
 * Vault-Tec lunchbox, on a couch on the 3rd floor in a waiting area, next to a baby stroller.
 * Syringer on a countertop in the northeast corner of the 2nd floor.
 * There's an elevator that leads up to the 7th floor, which has a suit of power armor that a Gunner Commander will get into if you don't get to it fast enough. The Gunner who uses it is directly behind it sometimes, but look to the right of the power armor before you move out of the elevator. Be ready to shoot fast! Freezing weapon recommended to make this much easier.
 * Bonnie's holotape, in the control room for the MRI scanner on the 9th floor.
 * High-powered magnet, two of them inside the compartment of the MRI machine on the 9th floor.
 * Brotherhood of Steel holotag, 7th floor on the corpse of a Brotherhood of Steel's scribe initiate, in a locked (Novice) holding cell.

Appearances
The Mass Bay medical center only appears in Fallout 4.

Behind the scenes
The location is likely inspired by the real world Tufts Medical Center which is located in the same position and shares some architectural similarities.

Bugs
Sometimes, when one enters the elevator to the roof and presses the elevator button, the elevator will close but then run forever, seemingly passing unlimited floors without end.
 * This may be related to the positioning of the player and their companion when starting the elevator. Having your companion get in first and move to the back of the elevator, and then issuing the stay command, will normally prevent the bug from occurring. The elevator should pass about four floors on a regular trip - if yours goes beyond 5 or 6, you've likely encountered the bug. Jumping around inside the elevator might cause it to become "unstuck".
