I know where you mean, often had rogue groups trying to survive the manhunt up there, we tried it too, however the whole server comes after you & we never made it, trying to hold off 18 people seemed near impossible when you have to reload/revive team members etc, good fun tho.
Did anyone manage to survive a manhunt? I know the rewards are supposed to be good, but what happens when the timer ends? if you get the rewards & your still rogue your probably going to get killed & lose a big chunk of them.
Also we noticed theres a range limit on turning others in your group rogue, we were split into 2 teams at one point on opposite sides of an extraction & 2 went rogue the others didnt.
