- 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.
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. 表达式错误：未预料的<操作符
- 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.
