The Greater Mass blood clinic is a location in the Commonwealth in Fallout 4.


The building is infested with bloatflies and bloodbugs. The walls and floors have numerous holes allowing the insects to travel easily between floors and sections in ways that humans cannot always follow. There are three main sections of the building, and getting between them can require leaving the building and going around the outside - the entrance, a "left" section with access to the upper floor with the locked lab behind a terminal, and the "right" section allowing access to the basement and storage room behind an expert level locked door. It is possible to drop through the floor of the upper section to bypass the locked door, and in the basement a password can be found to bypass the terminal and reach the lab.

A high level infected bloodbug guards the basement section, and can be difficult for a lower level player to defeat. Apart from the bloodbug, the building contains a large number of blood packs in the basement.

Notable lootEdit

  • Massachusetts Surgical Journal issue #4 - On the second floor behind terminal-protected security door.
  • A large number of blood packs (20+) can also be found in the basement.
  • Syringer rifle - In the basement.
  • Three blood clinic keys - One is on a desk in a small room on the second floor. Another is on the ground floor next to a corpse by the southwest side door entrance (on the inside of the building). A third key can be found in the basement on a desk in the room before the lab/blood storage room. Opens the outside door and the safe in the lab.
  • Blood clinic password - Inside a novice locked terminal on the ground floor close to the southwest side door entrance. Opens locked lab room.
  • South of the clinic is a group of warehouses and the eastern-most one contains a partially complete leveled set of power armor. This warehouse also contains four power armor stations.



The Greater Mass blood clinic only appears in Fallout 4.
