GRE Quarantine locations are accessible at any time, but you should only venture into them at night. During the day, they’re very difficult (almost impossible) to explore because of the number of Infected and Volatiles inside. At night, these numbers dwindle.
You begin these areas on the top floor and venture down. As you explore and make your way deeper, be sure to open up the side doors and shaft doors to make escape routes between floors if Infected overwhelm you or day approaches. Daytime levels of Infected will automatically start to spawn when the sun rises, even if you begin GRE Quarantines at night.
Try to use stealth as much as possible in these locations to not get swarmed. Also, be aware that some locations have Goons and harder-to-defeat enemies than simple Biters.
Each location has 4 Inhibitors in it. There is one Inhibitor on the first floor, one on the second floor, and two on the third floor. You only have to find three GRE containers, though; the first two are in singular GRE containers each, and two are in the last container.
These containers are locked behind GRE “airlock” doors. Often, there are two or three of these doors into a single Inhibitor room but always look for the blue wire attached to one of the doors. That indicates the door you must lockpick. GRE Quarantine locations are also worth returning to because like other Inhibitor chests around Villedor, these can be farmed over and over for gear, Military Medkits, and Immunity Boosters, making these easy, consistent sources of these supplies when in need.
Lastly, there are also Tape collectibles in each of these GRE Quarantine areas, always on the desks across from the first Inhibitor container.
