Z-9 Crotalus DNA Preservation Lab

The  is located directly 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.

Notable loot

 * 8+ Nightstalker squeezin's
 * Auto-Doc Upgrade: Implant Y-3 on a operating table in the main room.
 * 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.
 * 2 or more Proton throwing axes can be found in or near the caged nightstalkers
