Greenetech Genetics is a location in the Commonwealth in 2287.


The building cannot be accessed before the quest Hunter/Hunted (the door is non-interactable until then).

First floor

Contains a small reception area with broken stairs to some catwalks. To the north are functional stairs leading to the second floor. There is also a lobby to the west that is only accessible from the second floor. There's an unlocked terminal on the ground floor of the lobby that controls some turrets.

Second floor

Contains catwalks leading northward to a hallway with some offices, then curls around to stairs going up.

Third floor

Contains bathrooms in the northeast corner and offices to the north. A ramp on the southwest side leads to the next floor.

Fourth floor

Contains a Novice locked terminal that controls some turrets, followed by a catwalk that leads across to the east side and into a lab area and kitchen. Past the kitchen is a Novice locked door that leads to a mini armory with a trapped chest. Down the hall is another ramp leading up.

Fifth floor

Starts in a lab area. To the north are a couple of offices; one of which holds a Stealth Boy. To the west is a catwalk that heads to the other side of the lobby, with a hallway leading to offices on the north side and back around to the east side, where the stairs to the next floor are located.

Sixth floor

A trapped stairwell to the seventh floor.

Seventh floor

Contains a lab area with an Advanced locked door to the west, as well as a security control terminal and a safe. Just to the south is a room with stairs going up and an elevator, above a couple of small storage rooms.

Eighth floor

Immediately after the elevator, there will be a Master locked terminal that opens a security door to a room with 2 fusion cores. On the other side of the room, just before the stairs, is an Advanced locked door that leads to a room with another fusion core. Just before the stairs leading up, there is another Master locked terminal with a fusion core and Rad-X behind the door.

Ninth floor

Contains a pair of locked terminals leading to minor loot in side rooms. Through the door to the south, stairs in the southwest lead to a desk with a broken terminal and a small caps stash next to it. The stairs in the south lead up to the final floor.

Top floor

Open area with a side room that's locked during the Hunter/Hunted mission and stairs leading up to the roof. There is a Fat Man on the stairs. During the Hunter/Hunted mission, there is a mini nuke under the stairs.


An ammo box and a doctor skeleton are found on the roof.



  • On the third floor in the restrooms (northeast on the local map), there are wooden blocks on the floor behind the stall doors that spell "Gary", a nod to Vault 108 in Fallout 3.
  • On the fifth floor on a console desk there are some wooden blocks (I & D and B & Y) as well as an eight ball and knife and fork. They spell out I 8 U.
  • On the fifth floor, there is a blackboard with three bullet holes in it. Below the bullet holes are old, dried bloodstains. To the side are three chalk X's, just as seen on the Fens Phantom's displays in the Fens Street sewer.


PC If you've completed the Hunter/Hunted quest (where you kill the courser), it may cause the cell (a few blocks in all directions of Greenetech Genetics) to be bugged so that when entering that area, you cause the game to crash. It doesn't matter which direction you approach from. [已核实]

  • On the ground, determine the exact threshold, then save, then turn around, look straight at the ground and move backwards (looking at the ground). This may get you past this bug (on the ground) but if you enter any building in that bugged area, you cannot exit via the door; use coc and the location you wish to travel to.


Greenetech Genetics only appears in Fallout 4.
