I was wondering how many vaults there are in the fallout series like how many you go in or if they talk about any. AND (LoL) how many are there in fallout new vegas that you can actually walk into?
There are six vaults in New Vegas: 3, 11, 19, 21, 22, and 34
The stories to the vaults in New Vegas:
Spoiler
Vault 3 was attacked by a raider gang called the Fiends Vault 11 had to sacrifice one person a year - if they didn't, the main computer would shut down the vault Vault 19 was split in two - completly symmetrical, a Blue side and a Red side Vault 21 was the gambling vault - all disputes were settled with gambling. After Mr. House retook the Strip, V21's overseer played House in blackjack. If the overseer wins, 21 remains independent. If House wins, he gains control of 21, and remember - The House never loses. Vault 22 researched spore plants, the plants overgrew and killed everyone inside Vault 34 had an overstocked armoury with no lock. The overseer restricted the weapons from use, so an angry group of vault dwellers went on an exodus out of the vault. They eventually settled in Nellis AFB. They are now know as the Boomers - a xenophobic group that launches artillery at anyone who approaches their home.
