Vaults are a key part of the Fallout universe. Some contain horrific and twisted experiments, while others are actually shelters for their dwellers. Good or bad, nightmare or safe haven, these are all of the vaults in Fallout.

Every Fallout Vault (in text form)
Vault 0 is located in the Cheyenne Mountains and can be found in Fallout Tactics. It had no experiment, it just expanded upon the Cheyenne Mountain Complex and was a sort of headquarters of all the vaults. Many pre-war geniuses were cryogenically frozen here. It is eventually taken over by The Calculator.
Vault 1’s experiment was unknown, but it was located somewhere in the Great Midwest Commonwealth and was the first vault commissioned by Vault Tec following the success of their Los Angeles Test Vault. It appears in the tech demo for the cancelled Fallout 3 by Black Isle Studios. (roughly 17 minutes in)
Vault 3 is located in the South Vegas Ruins in the Mojave Wasteland. It was a control vault, so it had no experiment. Some time after the Great War, a water pipe broke, forcing the door to be opened. Soon after, the Fiends took over the vault and killed the dwellers.
Vault 6 is located in Mount St. Helens in Washington. It isn’t in any game, but it would have appeared in the cancelled Fallout Extreme. It’s experiment involved releasing small amounts of radiation into the vault every day, slowly turning the residents into ghouls.
Vault 8 was another control vault located in Nevada and can be found in Fallout 2. It had minimal issues, opened after 10 years, and eventually became known as Vault City, which is a thriving community and one of the most advanced non-isolated communities in the wasteland.
Vault 11 is located a little west of Boulder City, Nevada and can be found in Fallout New Vegas. The vault’s experiment involved dwellers sacrificing one of themselves every year to avoid an “Automated Solution Response” from killing them all. Sort of a test to see if someone would sacrifice themselves for the greater good.
Vault 12 is located underneath Bakersfield, California, and is found in Fallout. The experiment required that the vault door not completely close, allowing radiation to slowly seep into the vault. It eventually became part of the ghoul-town Necropolis.
Vault 13 is located beneath Mt. Whitney in California, and is found in Fallout. The vault’s experiment was to test prolonged isolation, with the vault being closed until Vault Tec decided the subjects were needed, which was supposed to be around 200 years. The water chip failed, forcing the Vault Dweller to venture out into the wasteland to find a new one.
Vault 15 is located in what has become New California, and can be found in Fallout and Fallout 2. The experiment was that everyone inside had drastically different ideologies, which lead to a schism, where four groups left the vault and eventually became the Jackals, Vipers, and Khans, with the fourth founding the village of Shady Sands.
Vault 17 is located somewhere in New California, and is only mentioned in Fallout New Vegas. In 2154, it was raided by the Master’s Army. Only Lilly Bowen, Becky, and Jimmy survived. When Lilly was 75 years old, she was captured and turned into a night kin by the Master’s Army.
Vault 19 located southwest of the remains of McCarran International Airport in Nevada, and can be found in Fallout New Vegas. The vault’s experiment had the vault dwellers be separated into two groups, with little to no contact between them. After a leak in the ventilation system caused paranoia to grow, the vault became abandoned and is used by the Powder Gangers.
Vault 21 is located beneath New Vegas, and can be found in Fallout New Vegas. The experiment was that all differences were settled by games of chance, and the dwellers were all compulsive gamblers. Between 2271 and 2281, Mr House took over the vault after the dwellers let the future of the vault ride on a game of blackjack, which they lost. Mr House then destroyed most of it and turned it into a hotel.
Vault 22 is located northeast of Jacobstown in Nevada, and can be found in Fallout New Vegas. There was no experiment, just scientists studying plants. A fungus from Big MT was brought in, which quickly infected everyone and turned them into spore carriers.
The rest of the Vaults wouldn't fit in the description. Whoops.
