To gain access to the interior of this bunker , the Courier needs to either have a Lockpick skill of 100 ( Very Hard ) or perform certain other actions to be able to interact with the intercom , such as : Using the BOS password or picking the lock will cause a Brotherhood of Steel squad to appear and confiscate the Courier ' s entire inventory . A short scene follows in which the Courier is questioned by Senior Paladin Ramos about the password itself . A meeting with Elder McNamara follows and the first quest is assigned . The elder will explain the secretive nature of the location . The Courier is fitted with an explosive collar , which will detonate after passing beyond a certain range of the area . After exiting the elder ' s chamber , the Courier is confronted by Head Paladin Hardin who believes the elder ' s policy of keeping them isolated from the outside world will be their doom and wants help in ousting Elder McNamara . He asks the Courier to find out more about what leads to an elder being replaced and requests an update on all the quests given by the elder . These are all marked as optional parts of the same quest . Obtaining the holotapes . REPCONN headquarters . Once finished with the tour , enter the door to the left in the planetarium and up the stairs to get the keycard . Go back to the first room and through the locked door using the card . Find the door to the second floor and take the first door on the left . Hack the terminal ( Very Easy ) , beside a , and select the first option which gives unlimited access to the second floor . Find the door heading to the third floor and enter . If a Luck ( 7 ) or Intelligence ( < 3 ) check by a security robot is not passed , it will tell the Courier that they must leave in 30 seconds . Search the paladins near the rubble for the mission statement ( Matiz ) and leave ( there is also a 3rd Level security pass located in Piers Isley ' s briefcase , next to his skeleton ) . Nellis Air Force Base . The location of the paladin can change from game to game because of the artillery the Boomers fire when the Courier first approaches Nellis . Here is one probable location : After the Boomers stop bombing , stand at the entrance to Nellis . Head south - southwest up the hill and pass between the car and road barricade . There is a bombed house directly ahead . Continue south - southwest down the road to the house next door . There is a backyard behind that house bordered by a wall with ornamental decorations . In the backyard , there is a crater with a car in it . The paladin ( Raseleanne ) should be in or nearby that crater . Take the mission statement from her . To pass the bombing , don ' t do as the note says . Just run left toward the fence staying as close as possible to the rocks and go along the fence to reach the gate . Black Mountain . After exiting the Hidden Valley bunker , aim directly in between northeast and east on the Pip - Boy compass . Follow this to a hole in the fence and follow the trail left to Black Mountain . It is possible to access the cage from Black Mountain with a Lockpick skill of at least 75 . The gate is just behind the radio station . This is where Moe and possibly 5 - 6 additional centaurs are located , in and around an irradiated crater ( + 1 - 11 Rad / sec ) . The paladin ( Fairbanks ) holding the mission statement is at the bottom of the crater . Return to the bunker and hand over the tapes to McNamara , or talk to Head Paladin Hardin who will accept the holotapes and use them as evidence to oust McNamara . Ousting McNamara . ( Optional ) If the Courier chooses to help Head Paladin Hardin , start by researching previous elders ' dismissals in the scribe archive data store . Doing this requires the problem with the Hidden Valley computer virus to be resolved . Speak with Scribe Ibsen about fixing the virus . After the virus is isolated , consult the datastore , then talk to Paladin Ramos about ' The Chain that Binds . ' He will authorize access to this information in the data store . Return to the archives and read about ' The Chain That Binds . ' Talk to Hardin about this newfound information . He will say that things will take a few days . The screen will go black , and when the scene resumes , he is now Elder Hardin . This will effectively conclude the quest , eliminating the need for further steps . Hardin will give the Courier a key to the Brotherhood of Steel safehouse . Scouts . After giving McNamara the holotapes , he will ask the Courier to find 3 scouts . Head to each scout and start a conversation ; the first option should mention " Are the bears still hunting ? " Choose this to receive the scouts ' reports . Collect all three and give them to McNamara . The first scout is located on the northeast end of the NCR Correctional Facility , relatively close to the facility and relatively low to the ground . He is just outside the fence bordering the facility . After asking him if the bears are still hunting , he will report that he ' s been watching the NCRCF for a while now , and is confused as to how the NCR has let the Powder Gangers remain loose and in control of the jail for this extended length of time without any attempt at retaking the prison . Or , if the NCR has retaken the prison , will express his surprise that it took them so long . The second scout is on the far northeast side of Nipton , quite far off and very high up . The water tower in Nipton is visible far off ahead on the right side of the town of Nipton . Head north - northeast from the water tower and scale the mountain ( between and a little north of the Coyote Den and the Hidden Supply Cave ) , and remember that it is not close to the town . When inquired about the hunting bears , he will give his report on the brutal attack on the town of Nipton by Caesar ' s Legion , and the fact that it happened so deep in NCR territory . With low reputation with Caesar ' s Legion , Legionary assassin s may spawn around this area . The third scout is easier to find than the second ; he is located to the southwest end of the NCR Camp Forlorn Hope . He is up on a rock overlooking the valley on the southern side of the camp , in plain view of the Ranger tower on the far south side of the camp . The rock which the scout is on is not adjacent to the rocks surrounding the camp ; there is a large gap in between the rock that the scout is on , and the Ranger tower on the southern side of the camp . The rock is approximately the same elevation as the ranger tower , although slightly higher in elevation . He cannot be seen from the Ranger tower ; go up the rock to find him . His report is on the town of Nelson and the NCR defeat there . Return to the bunker and give the reports to the elder . He will ask the Courier to speak to Senior Knight Lorenzo about repairing the air filtration system . Fixing the Air Filtration System . Vault 22 . The 6 HEPA 20 cartridge filter s are in a locker on the " 2nd Level - Oxygen Recycling " , in the same level where one can find Keely after rescuing her in the side quest There Stands the Grass . The filters are only accessible via the caves because debris blocks the doorway to the room they are located in ( through the door that says " key required , " with a terminal next to it , one must first acquire the keycard located below ) . Firstly , navigate towards the " 4th Level - Common Areas " . Head into the upper atrium and drop down to the level below . From here , go through the door labeled " Quarters . " An Average lock is on this door but can be bypassed by using the terminal in the overseer ' s office on the 4th floor . Be wary of the corridor , as there are several spore carrier savage s . A Vault 22 cave door keycard is in the first room on the left ( the one with a baby carriage and crib ) with a couple of spore carrier savages . Look on the shelves to the right of the room . The keycard is on the second shelf from the bottom . When the keycard has been obtained , head back up to " 3rd Level - Food Production " and enter the room with a terminal and the cave door ( the door cannot be lockpicked and requires the keycard ) . Use the terminal on the left to unlock the door . Upon entering the cave , take the first right and head up that path . There will eventually be a wooden door labeled " Oxygen Recycling " ; enter this door . The 6 HEPA 20 cartridge filters can be located in a locker here . Finally , go back into the cave and retrace the Courier ' s steps to go back to the first level " Entrance Hall , " and proceed to the vault exit . Alternatively , take the lift down to Pest Control , turn left up to the stairs to a door to Food Production . The Courier will find themself in some caves . Go up the slope taking the first right , following this until the door to Oxygen Recycling . Vault 3 . Upon entering the vault via the control panel next to the door labeled " Vault 3 recreation center , " in the South Vegas ruins , the Courier will encounter a Fiend who asks their business inside the vault : Vault 11 . One will find the differential pressure controller in a locker underwater in the flooded section of the lower level . It ' s helpful to have the rebreather from the Boomers quest Volare ! for this . Go towards the overseer ' s office but before reaching it , take the turn towards the utility room and head down the stairs into the flooded hallway , keep going and take the first room on the right and it ' s in the locker on the right hand side of the room . See the quest " Democracy Inaction " for a detailed guide . Here ' s a quick run down : When entering the vault open the first door . - Take the first door to the right . - Go right again down the stairs - Walk past the 2 closed doors and go down the stairs - Go straight and follow the stairs downwards into the living quarters . - Follow the stairs down until reaching the big room with 3 routes . - Take the door with admin written on top - At the end of the hall take a right to the overseer ' s office - Take the door to the lower levels and follow the steps down - Before entering the overseer ' s office take a right - When there is a sign with utility take a right again and follow to the end of the hall ignoring the 2 doors . - This is the flooded area , yet it is not completely flooded so one can breathe easily by swimming to the top . - Swim down the stairs , take a left and take the first room on the right . In this room , one will find the differential pressure controller in a locker to the right of the entrance . ( To the left of the entrance is a first aid box containing random aid items ) . Once all three items have been obtained , return to Hidden Valley and tell Lorenzo . He will tell the Courier to return to Elder McNamara . They will receive 1000 XP and a Brotherhood safehouse key in return . Upon re - entering the Hidden Valley bunker the Courier will have access to a special footlocker by the entrance that re - stocks energy weapon ammunition every time one re - enters the room ( A Brotherhood scribe will speak to the Courier and tell them , causing a box to appear there ) .
