Hidden Valley Bunker

The Hidden Valley bunker is a location in the Mojave Wasteland. There are several 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. It can be distinguished from the other bunkers in the area by the small broken tree stump directly on top of the dome.

Exterior
The bunker is marked by a small broken tree stump directly on top of the dome. You will not be able to gain access to this bunker unless you have taken the holotape containing the passphrase from the two dead Brotherhood of Steel Paladins at the REPCONN Headquarters, the one near Black Mountain, or the 2 dead Brotherhood soldiers in a ditch on the artillery battered area outside Nellis Air Force Base.

If you have the holotape and passphrase, you will be given the option to say it into the intercom. Otherwise you can attempt to pick the Very Hard lock (lockpick 100) or by having follower Veronica Santangelo with you. Access can also be granted through the quest Wild Card: Side Bets or by advancing far enough into any storyline to be asked to investigate the BoS.

Interior
The facility is divided into an entrance area and two main levels. The Brotherhood of Steel Paladins will respawn after a couple days, if players are planning to take it 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 (you need a lock-pick skill of 100 to unlock it) is a empty room with open doorways to the left and right, which is guarded by at least two stationary Paladin on the opposition wall. They do not appear if you have brought Veronica with you. The doorway to the left leads to a small office with a desk and a computer terminal, while the doorway to the right leads to stairs 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 a school/educational room where initiates are trained.

After turning right down the set of stairs into the bunker, turn left, then right, and there are 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, an archive/computer room for the Scribes, a workshop for the knights to repair and manufacture equipment, and a room containing VR chambers which seem to have been placed around the bunker's main reactor.

The Second Floor has the Brotherhood of Steel logo 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. Further down the hallway is where you find Head Paladin Hardin; he can be found in either of the two rooms beyond the first room.

The east area has the archive computer terminals, the Machine shop and the Virtual Reality pod room. The Virtual Reality pod room has both Head Scribe Taggart and Apprentice Watkins; it also houses the self-destruct authorization terminal and the self-destruct terminal (locked - Very Hard). Alternatively, terminals on the same floor of the bunker will give you a password. If you successfully hack the terminal or obtain a password, you can initiate a self-destruct sequence that will immediately vilify you with the Brotherhood of Steel and causes all Brotherhood of Steel members to become hostile. You can abort the sequence by reactivating the terminal and choosing to abort, but this has no effect on their hostility to the player at this point.

Notable loot

 * Knight Torres, at the shooting range, has the key for the door that is on the sub level of the shop-counter. However, sometimes the key is not needed as the door is already unlocked. With the key, you can access the shop from the door below, stealing four near perfect sets of T-45d power armor and three T-45d power armor helmets, as well a few rifles and ammunition.
 * In the white plastic bin by the desk in Schuler's office. Bunker L1, west of the central hub corridor junction a Nikola Tesla and You can be found.

Appearances
Hidden Valley bunker appears in Fallout: New Vegas.

Bugs

 * If you found and killed a few of the paladins and later bring Veronica they will accept you and let you see the elder. However, you will be trapped in the room and the only way to get out is by pickpocketing the key from the guards. Later upon opening the door, all the paladins and alike will attack you. If you leave L2 all of your stuff will be removed (including caps) and there will be no way in getting them back.
 * The paladin sitting at the shooting range may go missing. His reference ID is: - use the console command  followed by . He then returns with his helmet on.


 * About three or more Brotherhood Paladins my spawn in the same shooting range stall and get stuck there trying to shoot at the target dummy. This may cause one of the Paladins to drop his/her Gauss rifle on the floor next to them. Though the weapon says "steal", it will not have an affect on your karma, your position with the Brotherhood, nor will any of the nearby Paladins seem to notice you taking the weapon.
 * By zoning out and back in the locker will be refilled with various ammunition, allowing you to collect an unlimited amount of energy ammunition (by constantly zoning in and out) and convert the ammunition into other types of energy ammunition, or even max charge ammunition at the workbench on Level 2.
 * The merchant may begin to lag when asked to see her wares. The merchant will repeat her lines 2-3 more times before the item menu appears.
 * Inhabitants may react to firing exercises on shooting range as real combat and be unresponsive to attempts to communicate.
 * Veronica may repeat any sentence said on the intercom repeatedly, thus making her unable to converse with. This can be fixed by reloading a save.
