Fallout: New Vegas locations project
Z-9 Crotalus DNA preservation lab
The facility is directly northwest of the X-8 research center. Entering the main door into the lab, there is a three-way fork. Going forward and then left, there are cell cells each containing cages, likely for night stalkers considering the large amount of egg clutches and night stalkers present in the area. Each cell contains a small amount of loot, most common food items and some miscellaneous good such as night stalker eggs/blood as well as some tin plates. One cell contains a lobotomite mask on the head of a corpse.
Heading straight then right from the main entrance will take the player into a lab area which is joined onto a caged observation area. In the lab section, there is some computing equipment and a few crates containing assorted loot as well a sample crate containing night stalker eggs, blood samples and squeezins'. In the caged area, two night stalkers will spawn. The player can open the gate and go into this small area which contains only a cabinet and a crate containing assorted loot as well as some tin plates lying on the floor of the area.
Going straight forward from the main entrance will lead the player into the main lab area. In this area, there are three operating tables with saw blades as well as assorted surgical implements such as bone saws and tweezers lying on the table. On the floor of the lab there are a few egg clutches which contain night stalker eggs. At the back of this lab there is a electric hot plate. On the left of the lab entrance there is also a chemistry set which can be used to craft stimpaks or assorted chems. In this lab area, the unique night stalker Shadis will spawn, and it will be protecting the Y-3 implant.
- 8+ nightstalker squeezin's
- Auto-Doc Upgrade: Implant Y-3 on a operating table in the main room.
- The area has several nightstalker egg clutches and each of them has several eggs in it. This makes this a good place to collect some of the eggs you need for Bleed Me Dry quest.
- Two or more proton throwing axes can be found in or near the caged night stalkers.
Behind the scenes
Similar to the Z-14 Pepsinae DNA splicing lab, the name Crotalus refers to crotalus, a genus of pit vipers indigenous to the Americas, which include the rattlesnake, which is part of the night stalker DNA.
