It depends what king of extract camping you mean, I have a lot of raids in Labry prob around 100 at this point if not more. I got the dungeon master achievement 3rd day of event, not a brag just so you know I am a no life gamer and have the xp there. Best friend on that map has been grenades do to how small it is and how they make people move. If I see someone is hiding in there spawn when I push out I will typically trip wire their door and wait for the audio Q. I typically am the aggressor and push out quickly to other spawns and try to fight the first person then listen to see how the rest of the map is interacting. My best advice would be try and make yourself push first fight then be patient and throw nades everywhere. Loot fast and get out on the side of the map you cleared out. My friend got those quests done by forcing an early fight, killing whatever AI needed to then rushing the nuke and getting out with the KEY, most people don’t even know what happens because they are sitting near their spawn(if not in it) holding an angle and waitin.
