Hidden Valley

 is in a fenced-in area nestled between hills and rocks roughly North-East of the NCRCF and South-East of Sloan. The valley is home to four bunkers and numerous bark scorpions. Hidden Valley is also the home of the remnants of the Brotherhood of Steel that once occupied HELIOS One.

Every night, a violent dust storm occurs making it hard to see enemies - night vision weapons and Boone's Spotter Perk will help.

Accessing Hidden Valley
Hidden Valley can be accessed via the road near Sloan and at the northwest and southeast corners where the fence is down. There are small side-paths, at least one of which is heavily inhabited by bark scorpions and the occasional Giant Radscorpion when going in the direction of Scorpion Gulch nearby. It is advised not to approach the sandstorm at night, as a Brotherhood patrol will most likely be out and WILL be hostile. Unless you are a high enough level and well-equipped, they are extremely dangerous.

Layout
The four bunkers are spread around the perimeter of the area. Three of four bunkers are just a large entry room with a locked door on the opposite side that lead to nowhere, but may contain some notable loot.


 * East Bunker: The entry room has 3 skeleton's with a bottle of wine on a sleeping mat. The locked (Easy) door in this bunker hides a hundred 5mm rounds and twenty four 5.56mm rounds.


 * North Bunker: This entry room has a wooden-crated yellow barrel holder on the left and large metal storage containers on the right. The locked (Average) door are a pair of Mini Nukes, a Stimpak, and some 5.56 ammo.


 * South Bunker: This bunker has a grenade bouquet hanging from the ceiling at the bottom of the staircase. The entry room contains a sleeping pad and a sack, along with a journal indicating that someone is using the bunker as a safehouse. The locked (Hard) door here opens the way to 3 ammunition boxes, a Mini Nuke under a Tin plate which you will have to move in order to see, a steam gauge assembly and 2 units of scrap metal on the right, and a frag grenade and some 5.56 ammo on the left.


 * West Bunker: The fourth bunker is the Hidden Valley Bunker - home of the Brotherhood of Steel. The bunker is marked by a small broken tree stump directly on top of the dome.

The Brotherhood of Steel
In one of the bunkers is the Hidden Valley Bunker - the secure home of the Brotherhood of Steel. You will not be able to gain access to them 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, the PC will be given the option to say it into the intercom. Otherwise you can attempt to pick the Very Hard lock or by having follower Veronica Santangelo with you. You can also gain access through the quest Wild Card: Side Bets.

WARNING!
 * Going into the BoS bunker wearing any type of NCR armor will make the paladins immediately hostile.
 * If entering the Brotherhood secure area using the passphrase, you will immediately start the NCR Ranger task of the Still in the Dark quest. Your weapons and armour will be taken, but will be given back once you have completed this task. See Still in the Dark for more information. You may want to save prior to this.

Notable loot

 * A hollowed-out rock with a little ammo in it (and a heart painted on it) is in the central area, When you fast travel to the Hidden Valley the hollowed-out rock will be infront of you.
 * East Bunker: A bottle of wine on a sleeping mat. Ammo behind locked (Easy) door (i.e. a hundred 5mm rounds and twenty four 5.56mm rounds).
 * North Bunker: Behind locked (Average) door are a pair of Mini Nukes, a Stimpak, and some 5.56 ammo.
 * South Bunker: Grenade bouquets hanging from both the ceiling at the bottom of the staircase and in center of the main room. If entering this bunker after receiving the related task as part of Still in the Dark, the traps will be gone, but you will be stopped at the bottom of the stairs by the resident. Behind the locked (Hard) door is an Ammunition Box, a Mini Nuke under a Tin plate which you will have to move in order to see, a steam gauge assembly, scrap metal on the right, a frag grenade and some 5.56 ammo on the left.
 * After the Brotherhood of Steel Quest to rid the South Bunker inhabitant, you can find 3 boxes of .308 shells on a shelf on the left along with food supplies.

Appearances
appears in Fallout: New Vegas.

Bugs

 * In some cases. entering and walking down the stairs, after you get disarmed can cause crash to desktop repeatedly. This happens when wearing the rebreather, remove it before entering the bunker.


 * It is possible to become trapped after starting the quest Still in the Dark. Despite instructions from the elder to perform a task outside the bunker, the door to leave is locked and needs a key.  This was solved by pickpocketing a key from the head of security.


 * In the hill paths leading to Hidden Valley, it is possible to encounter deathclaws from Quarry Junction, including the dreaded Deathclaw alpha. It may pop out from under the hills or rocks.


 * Xbox 360/PS3 Users may not get their guns returned during the first encounter test, save before entering and meeting the Brotherhood for the first time.


 * If access the Brotherhood bunker with companions, but they're too far behind when you enter the bunker, they may spawn inside the bunker past the locked door rather than beside you. This can cause a blocking problem if you have Veronica Santangelo as a companion and the user is unable to use the intercom because of a scripted sequence. Because she spawned behind the locked door, the sequence never completes, and so the player can never get into Hidden Valley bunker.
 * Possible workaround: Use the console commands where x is the ID of your companion, and then  place the NPC next to the player.
 * Workaround: Exit the bunker and have your companions respawn next to you, and then re-enter. May require Patch 1.1.1.
 * Verified workaround: You should leave Veronica outside the entrace to the bunker. Just talk to her and tell her to wait there. Then You can enter the bunker and take the Still in the dark quest. Notice that You should NOT take her back until You will return to the elder to report the quest are completed.


 * In the South bunker if you activate the tripwire (which is attached to the grenades), it may kill you and freeze the game/console (PS3, others?)


 * After having the explosive collar equipped, and you are released to grab your items from the crate, the game may crash if you grab all items at once. To aleviate this, grab a bunch or all items one by one ( then try to grab all after you took a good chunk out) Occured running patch 1.1.1.
