There are 7 vaults as follows: Vault 87 Vault 92 Vault 101 Vault 106 Vault 108 and Vault 112
Vault 106 is one of the underground vaults by Vault Tech in the game that was used to store people when the nuclear bombs hit America. It is abandoned, just like all of the other vaults except for 101, which is where your character is from.
You can find the Science bobblehead in the living quarters of Vault 106 . It should be on a desk or table.
Yes, if you follow the main storyline you will finally meet him in vault 112.
you are born in the capital wasteland. your dad then moves into the vault 101. one day he disappears and you go out to look for him.
If your talking the ripper as a weapon then you can find about 7or 8 in Anadale . You go through it when you save dad from the vault.
There is many hidden quests in Fallout 3 but i there is one when you reenter the vault. (after you father dies) hang around the vault entrance.
vault 77 doesn't exist in the game.
They are scattered throughout the game, but I know there is one in vault 106. You just have to battle the insane survivors if you go exploring.
Just North from Vault 101.
All Vault Tech Vaults in Fallout 3 where made public. You are talking about private shelters that are scattered throughout the Capitol Wasteland.
