Abandoned BoS Bunker

Bunker 13 (simply referred to as the Abandoned Brotherhood of Steel Bunker in-game), is a reinforced subterranean installation that was used by the Mojave Wasteland chapter of the Brotherhood of Steel during their war with the New California Republic. It is the starting point for the add-on Dead Money. It is located slightly southeast of Camp Forlorn Hope.

Exterior
Standing on the metal grate to enter the bunker, directly to the east-southeast, is a hollowed-out rock containing random loot. If Dead Money is not installed, the grate will always be locked, cannot be picked, and the key to it doesn't exist in the game. However, in certain versions of the game prior to any patches, the grate will open.

Interior
The bunker interior is simple; the entrance contains a set of stairs leading to a main corridor from which two rooms can be accessed. There are several Sierra Madre Casino posters on the wall, and the graffiti at the entrance reads "Gone to Sierra Madre" and "I left my ♥ in Sierra Madre." There is a headless male corpse with some minor loot in the first room. This corpse is an immovable container, not a body, so although it appears to wear a Dead Money jumpsuit, one cannot be taken from it.

At the bottom of the stairs is a door. When the player character attempts to open the door, a warning appears about Dead Money, explaining that only experienced couriers should enter. Opening the door does not immediately start the add-on, allowing one to continue to explore the bunker. To the right after opening this door is a hallway that has collapsed into a pile of rubble and is inaccessible.

The corridor to the left after the stairs leads to a locked door, which can be unlocked by hacking the Average terminal found nearby. Once the door has been unlocked, a Sierra Madre vending machine will be found. The room also contains both a reloading and work bench, numerous crafting items (notably scrap metal, scrap electronics, and sensor modules), several bottles of Scotch, Elijah's chemistry set (which offers a Jar of Cloud residue every 24 hours), a laser rifle, a combat knife, a T-45d power helmet, and a Dean's Electronics skill book. The footlocker at the base of the bed (containing Father Elijah's robes) and the terminal on the desk cannot be accessed until after the completion of the add-on. Along one of the walls, someone has scribbled a series of mathematical formulas on a large blackboard.

A "drop box" (smaller version of a wall safe) can be found across from the wall-mounted terminal just outside the room. Every time upon entering the bunker again after being away for 3 days or so, there will be Sierra Madre chips and a complimentary voucher inside the drop box. If the player character won 7,500 chips in the Sierra Madre Casino, the voucher will be exchangeable for 1000 chips at the Sierra Madre vending machine. The length of time passed will account for how many chips and vouchers there will be in the drop box.

The room ahead consists of several bunk beds attached to the walls on both the left and right hand side, underneath each bed is a footlocker. Situated in the center of the room is a table adorned with an active radio playing the Sierra Madre Broadcast on an infinite loop. Walking into this room begins the add-on.

Notable loot

 * A copy of Dean's Electronics - On the shelf immediately to the right in the room with the vending machine.
 * Father Elijah's robes - In the footlocker in the bedroom.

Appearances
The abandoned Brotherhood of Steel bunker appears in Fallout: New Vegas and its add-on Dead Money.

Bugs

 * The bunker's exit hatch may say that a key is required to exit back to the Mojave Wasteland (thus becoming a prison), even after completing Dead Money. The solution to this is removing the system cache from your hard drive then starting up the game. Once it gives you the choice to update, click cancel and continue on from there. Load up your saved game and you will be able to exit the bunker back to the Mojave Wasteland. Once you re-update you will not be able to enter since a key is still required, hence you will permanently be locked out.
 * (may be due to last update) everything in the abandoned BoS bunker or any items from Dead Money are no where to be found, including stationary objects found like the old fashioned radio, Elijah's bed/vending machine, or obtained items like the automatic rifle and police pistol. This was caused by the localization of the add-on, as a person in Canada Needs French/English Canadian version, and with the pre-order add-on packs, the French version is required.
 * When the add-on is not installed, companions will sometimes fall out of the game upon entering the bunker.
 * Sometimes when saving while directly in front of the door that questions you about whether you want to start the add-on, loading that save will not load the door and instead have a gaping hole after it.
 * When trying to enter the abandoned Brotherhood of Steel bunker it will be locked and require a key but there is no key and reloading a recent save will not fix the problem. Deleting and reinstalling Dead Money or Old World Blues will fix this problem.
