There is no loophole. You can't build a Vault. Period. There is no way you can try and spin this to convince me because every argument you make tries to stretch the lore, which I will never accept. Finding the parts needed to make a Vault are nearly impossible to find and there are no working factories in the East Coast to make more other than in the Pitt. Plus, if the West Coast, which is more advanced than the East Coast, can't even make a Vault there is no way in hell the East Coast could do it.

Lore may not be important to you, but saying it isn't important is just flat out wrong.

Again as i said: but if we discover the secret, we discover the tools used for the manufacturing process, but we have only limited resources, hidden in a secret warehouse, and can be used for a limited small number of Vault: it is obvious that there is a loop.

What you're talking about isn't a loophole, it's a stretch. A vault isn't like legos, even if you magically found a place that had all the parts you needed (Which is a massive stretch as well as terrible writing) you couldn't build the freaking thing as easily as you think you could. The Commonwealth isn't capable of doing something like that and the only place that could actually manufacture some of the things you would need isn't exactly welcoming to outsiders unless you don't mind being a slave.

Like I said, great Idea for a mod, terrible idea for a dlc.

But the whole point of the vaults were to preserve human life for when Earth is livable again and to conduct experiments to see what the outside world was like. Neither of those are very useful now, because we the player have both lived out in the wasteland, facing literally all of it's new species, and are a pre-war human. The vaults were pretty much fancy bomb shelters, so in a world hundreds of years after the nuclear war where everyone has adapted to radiation and fallout, a bomb shelter isn't anyone's top priority.

Oh a stretch? Nevermind. My bad.

Btw i still think is possible built a vault by that way.

Like what Tlord has said, it's just not physically possible. We would need construction vehicles, supplies, a countless amount of steel, and years of work. Even if we had all of that, the plans for vaults were a pretty well kept secret. Renovating vault 114 might be better than 111 in my opinion.

Hilarious thread. I stand with Tlord's every word.

Hey what about my idea?

If you mean about the Memory Den when you said "you could play out the construction in the prewar past using the memories of a vault tec employee in the Memory Den. A quest could find his brain in V111 still preserved and let you go looking for the vault that he built", I'd still see that as taking over an existing vault, not building one outright.

Well, the things needed for a functional vault, goes way beyond some walls in a hole. I am no engineer, but things I would imagine a vault like that needs, is beyond the scope of just reading the info. I mean, we are likely talking;

Heating / Cooling, Massive Hydraulic shock absorbers, Air venting in / out, Special foundation, Drainage / Piping, Wiring, Reactor room with functional reactor (which alone would be more than enough of a task) Immense amount of reinforced steel and various other building materials, work vehicles for all the heavy labor (no way you are going to raise a steel wall that is heavy enough to withstand the earth by hand) you will need lifts, a working hydraulic system to the massive steel door entrance, and we could probably go on.

It is a novel idea, but I, also think the idea of using an existing vault is probably better, if going by lore and a bit of realism. Throwing that realism away with a mod would be the way to go (if there ever will be such a mod)

It was never furnished before the bombs fell.

Sure. I think that would work without necessarily breaking lore because it's still not outright building the vault itself. Though IIRC there is a set number of vaults, isn't there? Then again, even if that's so, I'm not so sure it would break lore to introduce a built-but-unequipped vault that was never on the official list because it wasn't ready when the time came.

it's good

According to the wiki - "The total number of vaults is a government secret and has been lost; there were the aforementioned "public" vaults, which numbered 122 and an undisclosed number of "private" vaults. Information on whether Vault-Tec was an international corporation or strictly U.S. based, cannot be released due to Vault-Tec and United States federal regulations.[6] That said, Vault-Tec seems to have constructed some vaults in Canada. In a letter sent to a rejected D.C citizen the company offered to provide a list of "Vault-Tec facilities with available accommodations, in exciting locales such as Oklahoma and newly-annexed Canada."
