Lab Rat needs you to confirm some details in Gray Zone Warfare based on what you learned from the letter from The Brave mission. For this task, it's time to return to Hunter's Paradise and collect a biological sample.
Gray Zone Carnivore Quest. Collect Biological Sample from Hunters Paradise (GET A SAMPLE KIT FIRST)
For some Gray Zone Warfare players, this might be a new task that involves collecting a biological sample. You’ll need the right gear for this, which you can get from Lab Rat. Once you have that, it’s time to scour Hunter’s Paradise for a suitable sample and bring it back in one piece.
As Lab Rat tells you, the biological monster you need to find will be in Hunter's Paradise. The exact location of the monster will be in the middle of this location, between the Firing Lanes, the Dumping Area, and the Motel. It is a heavily guarded location, with multiple NPCs protecting it, and you may encounter other players in this location if you play GZW.
But before you go, buy the sample kit from Lab Rat. You can find it under the Tools category by her vendor. The kit is needed to collect a sample in GZW. Without this tool, you won't be able to bring back a good sample for Lab Rat to examine, and you won't be able to complete the quest. You could work on this quest while also trying to complete Up to Snuff and Guns & Ammo.
