Sierra Madre Vault

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

It is the last location The Courier will go before the end of Dead Money DLC. The Courier must make his way through the bowels of the Casino, passing Toxic-Fog, Radio signals and Holograms to end up in the main Vault room,

Layout
Outside the there are several Auto-Turrets, fields blocking the exit to the elevator and the door to Vault room.

The Sierra Madre Casino Vault is different from typical vaults. It only has one room inside it. Inside the actual vault there are 2 terminals and a generator by the door to shut down the security turrets. Opposite the door at the other end a terminal on desk that has message for Vera from sinclair, explaining how he knew what her and Dean were planning. There is also one for Dean on the terminal, but reading dean's causes you to be trapped within the vault and ending the game, then continuing to the last save. There is a screen where you can make contact to Father Elijah, that appears after reading Vera's letter. There is also table with some Sierra Madre Chips, pre-war money and 37 Gold Bars, that comes to 390,239 Caps value but also 1295 weight as each bar weighs 35.00. The Courier can take a maximum of 10 bars without being overencumbered. Lastly there is a first aid box with a wide range of chems and aid, and a cabinet full of Sierra Madre Armour. Also in this cabinet are 6 Stealth Boys.

The reason the vault tempts you with such treasures, despite the fact that you can't possibly carry all of it and still be able to move, is because it is trying to see if you, the Courier, will succumb to the same stream of human greed that has acted as the final defense for the Sierra Madre's stash. Only by accepting that you simply cannot carry all of the treasures and still be able to move, only this will get you some of the important treasures. This further pushes the bar on how much the dead money DLC tries to get past the boundaries of traditional games, which encourage you to stuff your pockets with everything you can hold. Being unable to return to the Sierra Madre after you leave prevents you from ever being able to collect everything. Therefore, The Vault has taken the liberty of making a suggested list of what you should grab and what you shouldn't.

What to take: Everything with 0 weight, even things you don't need. This includes chems, pre-war money, sierra madre chips, holodisks, etc. etc. The armor, IF it is better than the armor you have waiting for you back in the abandoned BoS bunker.... or if you want it as a souvenir. The rest of your carry weight threshold can go into those deliciously valuable gold bars.

What to leave: The stealth boys. 1 Weight might not seem like much, but those gold bars are calling, and you'll need to take only the bare essentials if you want as many of them as possible. The Sierra Madre armor IF it is not as good as the armor you have waiting for you in your inventory at the BoS bunker. Some players take it anyway as a souvenir. If you want to, go ahead.

Regarding your inventory: Your Dead Money inventory will probably have stuff in it already by the time you get to the vault. Here's what to clean out before you leave: Armor you don't use: That Dead Money jumpsuit won't be of much use when you get back to the main game, and the sierra madre armor is a much better alternative if you want souvenir armor. Food and chems with weight: Seriously? You don't have enough potato crisps and purified water back at home? Weapons: This one's tricky. Most of the Sierra Madre's weapons, like the knife spear, are of little use in the main story, but your trusty holorifle and cosmic knife can be upgraded into some of the best weapons in New Vegas if you hang on to them. Consider it. Junk: Duh.

Whatever you do, do not, I repeat, DO NOT get greedy and grab so much stuff that you get overencumbered. It's a long way back to a place where you can sell your gold, and even farther if you don't have the Long Haul perk, which allows you to fast travel even when overencumbered. C'mon, that's exactly what the vault WANTS you to do.
