Z-9 Crotalus DNA Preservation Lab

The Z-9 Crotalus DNA preservation lab is located north west of the X-8 research center in the Fallout: New Vegas add-on Old World Blues. There appears to be nothing of great importance in here except some very tough nightstalkers and a lot of nightstalker eggs, tails, blood samples, etc. along with the notable loot below. The Auto-Doc Upgrade: Implant Y-3 is guarded by the named nightstalker, Shadis.

Layout
Entering the main door into the lab, the player character can go in 3 directions. Going forward and then left, there are 4 cells each containing cages, likely for nightstalkers 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 misc 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 forward and 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, 2 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 3 operation tables with saw blades as well as assorted medical items such as bonesaws and tweezers lying on the table. This area also contains a box of sample. On the floor of the lab there are a few egg clutchs which contain Night-stalker eggs. At the back of this lab there is a hot plate crafting location. 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. As well as the other assorted loot in the crates spread around the lab. Just outside of the lab are 2 cells rooms. One cell contains a lobotomite mask on the head of a corpse.

Notable loot
