Hidden Valley bunker The Hidden Valley bunker is a in the Mojave Wasteland . There are four similar - looking bunkers located close to each other in Hidden Valley , southeast of Sloan in the Mojave Wasteland . One particular bunker is the entrance to the home of the Brotherhood of Steel . It is directly northwest of the fast travel location ( center of area ) with a small broken tree stump directly on top of the dome . Layout . Exterior . The bunker is marked by a small broken tree stump directly on top of the dome . There is a marked with a heart and " no bomb " graffiti located to the west of the entrance to the bunker ( This is also the fast - travel point ) . The cement wall around the bunker ' s door includes these graffiti , as well as graffiti that reads , " BAN THE BOMB , " " GIVE PEACE A CHANCE ! ! ! , " and several others . Approved , unaccompanied access to the bunker cannot be gained unless at least one of the holotape s is recovered from either the two dead Brotherhood of Steel Paladins at the REPCONN headquarters , the Paladins in Moe ' s crater near Black Mountain , or the two dead Brotherhood soldiers in a ditch on the artillery - battered area outside Nellis Air Force Base . If at least one of the holotapes is in the inventory , the option to speak its pass phrase into the intercom will be available . Alternately , access can be gained by picking the lock ( very hard ) ( Lockpick 100 ) , by having Veronica Santangelo as a companion , through the quest , or by advancing far enough into any storyline to be asked to investigate the Brotherhood . If Veronica is not with the Courier , they will be contained , questioned , and forced to begin the Still in the Dark quest . Interior . The facility is divided into an entrance area and two main levels . The Brotherhood of Steel Paladins will respawn after a couple of days . If the player character plans to take over , it is advised to do so in one trip . Entrance . After entering the bunker there is a large entry room with a locked door on the opposite side , similar to all the other bunkers in Hidden Valley . On the other side of the locked door ( Lockpick 75 ) is an empty room with open doorways to the left and right , which is guarded by at least two stationary Paladins on the opposite wall . They do not appear if Veronica is present . The doorway to the left leads to a small office with a desk and a computer terminal , while the doorway to the right leads a staircase going down to the main section of L1 . Hidden Valley bunker , first floor . The first floor contains the personnel quarters , a shooting range , armory , medical bay , and an instruction room where Initiates are trained . After turning right down the set of stairs into the bunker , turn left , then right , until reaching two sets of Knight dorm rooms located one above the other with a set of descending stairs for the lower room . Each bed has a footlocker with a combination of a mid - condition laser pistol , energy cells , and / or microfusion cells . Hidden Valley bunker , second floor . The second floor contains the command room with living quarters for the Elder and Head Paladin Hardin . Located next to it is an archive / computer room for the scribes , a workshop for the Knights to repair and manufacture equipment , and a room containing virtual reality chambers which seem to have been placed around the bunker ' s main reactor . The second floor has the Brotherhood of Steel emblem on the wall , and two paths that go off to the east and to the west . The west area has the command room with Elder McNamara and another adjoining hallway . Head Paladin Hardin is further down the hall , and can be found in either one of the two rooms beyond the first room . The east area contains the archive computer terminals , the machine shop and the VR pod room . The VR pod room has both Head Scribe Taggart and Apprentice Watkins . It also houses the self - destruct authorization terminal and the self - destruct terminal ( very hard ) . Alternatively , terminals on the same floor of the bunker will give a password . If the terminal is successfully hacked , or the password is obtained , they can initiate a self - destruct sequence that will immediately vilify them with the Brotherhood of Steel and cause all Brotherhood of Steel members to become hostile . The sequence can be aborted by reactivating the terminal and choosing to abort , however this has no effect on their hostility . Appearances . The Hidden Valley bunker appears only in " " .
