Fallout shelter! That's the term I was looking for and you're right Vault 21 was in the Strip.

Umbrella Corp vault Resident Evil/Fallout crossover! Let the speculation begin!

Those aren't failed vaults. Those are the Vaults working as intended.

Remember - Vaults were never intended to save anyone. They were social experiments to test the Human condition under a variety of situations, with certain Vaults like Vault 8 being control vaults, that help research and function as intended.

A Proto Vault would be the demonstration Vault built in Los Angeles as a "proof of concept" for public consumption. That place eventually became home of the rapidly mutating Richard Grey, and eventually became the lair of the entity known as The Master, with the area above becoming the Cathedral.

Vault-Tec advertised Vault openings in "Newly Annexed Canada", so its entirely possible there are Vaults not in the continental United States. The European Commonwealth sounds like it devolved into anarchy too quickly to warrant a fallout shelter business, but I'm certain China had their own version of Vault-Tec.

Considering that the Outback was (albeit sparsely) inhabited by Aboriginal Australians prior to contact...

But Australian wildlife is scary enough before you mutate it; let's never have a game set in Australia.

I think the UK probably had bunkers of some kind but only for the 'chosen' few, I'm thinking government, military , royalty and useful people. I've see some of the UKs cold war planning and it's very cold stuff eg who was in charge of body collection and sites for mass graves

Also you have the value of the 'Class' of person in the UK which is still a thing. The upper class would have been in 'shelters' in the UK and no the common folk (middle to lower class).

In the original Fallout intro it states that the European Commonwealth dissolved into quarreling bickering nation states.

i see the dissolved into states as been more they went back to the countries they had been so the UK could have bunkers , especially since they are have been at war for years with nukes already been used

Yup. Its more than likely 'England' survived in some way. Of course that way might be a nastier version of what we see now.

In a way Im kinda sad the Fallout d20 pnp game was cancelled/ given the boot, as I think the rest of the world would of been a great sandbox for that game to flesh out. the Middle Eastern Countries, Australia , European Commonwealth etc.

Lets be honest, there is a lot of untapped potential for stories/lore with ANY of that. Enough for 100 games.

Id like to see the REsource wars game long talked about first.

Vault Tec was behind the bombing.

A lot of people are talking about what European countries may have done, especially the UK. If Beth sticks to established lore, the answer is probably not much. Most of Europe and the middle east were involved in a total war over oil and other resources that left most of the area both physically and economically shattered. Many nations didn't even exist anymore.

"The war came to an end in 2060 as the oil fields in the Middle East ran completely dry. There was no longer a goal in the conflict, and both sides were reduced to almost total ruin. The European Commonwealth dissolved into quarreling, bickering nation states, fighting over whatever resources had remained."

So Europe and the Middle East probably didn't do much for vaults. I wouldn't be surprised if China and the Soviet Union (which never fell apart) had something. Wealthy South American or African nations may have had equivalents, and possibly Australia. It all depends on how much they really expected a nuclear war.

I was always under the impression that Australia was completely lost in the Great War, and was the source of the "continents fell beneath the boiling oceans" line of the first intro.

There will have been Continuation of government bunkers in most states world wide. But some of these bunkers would have gotten flattened by nukes just because they were just that. Anyone who could rally a counterattack or resistence would be a strategic target.

Having said that, it would not be unlikely to find survivalists vaults. They exist today and are big business. The odd rich or higher class neighborhood might very well have elaborate private vaults.

However, given the tectonic shifts, tsunamis and other issues that seem to have followed the apocalypse, its somewhat impossible to know which ones survived and which ones didnt.

Without a doubt there would be other fallout shelters besides the Vaults going from real world examples. Vault-Tec would obviously be presenting itself as the ultimate in surviving the bombs which would have those be the highest demand, and since we don't really know what criteria they presented to the public as to how to get in such as buying a residence slot or filling out an application, that would leave a huge market out there for those not able to get in. Other companies making vaults are a possibility, though equally I can see Vault-Tec indulging in ample corporate shenannigans to either discredit or absorb the competition. Going from a quickie googlesearch, there did exist the do it yourself shelters which going from the blueprints I'm looking at, resemble more of an air raid style shelter than something that could withstand nuclear warfare.

I could see people doing the do it yourself shelters or going to a cheapy type shelter as an optioin, and those just didn't have the durability to survive the bombs and/or the passing centuries. For all we know when our characters go through what remains of a basemant with skeletons that it had or hadn't been a homebrew shelter.
