Sierra Madre vault

The Sierra Madre vault is a location in the Sierra Madre Casino.

Layout
The journey through the bowels of the Sierra Madre Casino are treacherous, filled with the Cloud, radio interference and multiple holograms guarding the way. After descending down the elevator in the executive suites, a short hallway leads to the vault area. However, force fields hinder advancing into the large open room. Instead, one is forced down covered hallways. To the south is a terminal next to a door; the terminal unlocks this door. This leads into a narrow utility tunnel. Soon after entering, the tunnel branches; on the right is a small alcove with a control panel and loose gun locker on the floor and to the left is the intended path.

The hallway leads into a medium sized two-storied room with a couple speakers. A stairway leads down and a radio signal begins to beep. The unguarded speaker is on the wall nearby. The stairway leads down to a canopied room with some ammo boxes. A safe zone from the radio broadcast is in the very westernmost corner of the 'room'. This room transitions into another multistory room with stairs leading up and several speakers mounted around the room. On the first floor there is a speaker on the north wall. On the second floor, one is mounted in the southeast corner, another is in the east above a door and a final is mounted opposite a terminal. The terminal is on the second floor's north wall and shuts down all the alarms (and thus the speakers).

Going through the door underneath one of the speakers leads into another utility tunnel. This tunnel exits to an open room occupied with three holograms and a couple of speakers. There is metal housing surrounding the west wall. Inside the housing is a terminal that alters hologram patrol programming. Another metal canopied room in the east corner also alters hologram patrol behavior, but in addition shuts off the speakerss and the security force field inhibiting advancement. There are three hologram projectors in all in this room. One is mounted to a wall in the northeast corner; another is on top of a steel beam above the floor; the last one is in the northwest corner on the metal housing above the terminals. There are two speakers in this room too; a protected speaker is on the east wall and an unprotected one is on the north wall near the door.

A utility tunnel guarded by a force field that must be shut down leads back into the vault area. A terminal inside the hallway accesses security information and can shut off the security measures (most prominently the speakers and force fields.

The vault awaits. Next to the door is a terminal which unlocks it, permitting access. Inside, there are scientific contraptions and a chemistry set on the left. On the right is a security locker filled with weapons armor and ammunition, a Sierra Madre vending machine and a table covered in pre-War money and gold bars. A terminal rests on a desk in the center back of the vault. A hidden screen is behind the Sierra Madre emblem which Elijah uses to communicate.
