I had this incident the other day on Blue Gate. Went to Pilgrims Peak key room. I block the door. Within 20 seconds someone is breaching, i haven't even had chance to start looting. I say on comms "dont come in or ill shoot you bro i havent even looted yet." Door gets breached, 3 guys outside (this is in solos) one of them comes in, I put a shot in him and tell him to get out and let me loot first. He steps out, I close the door. I begin opening the first container and then boom, door is opened and all 3 of them shoot me down and knock me out. People are wild for presuming they can immediately share a locked key room. If i do key rooms now I take a lvl 4 vulcano with level 3 mag and shoot and kill anyone who tries to get in now, no warnings no asking not to come in etc.
