it is inside a music practice room it is in a meatle case
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.
You can not go back in and out of Vault 101. After you first leave the Vault the only time you can go back in is for the quest "Trouble On The Homefront." but once you beat that side quest you are not allowed back in Vault 101 ever.
I think it is in the vault where you find the violin, Vault 87 There is also some sheet music in Springvale School in the music room.
You find him after completing "Tranquility Lane" in Vault 87. The vault is hidden in "Smith Casey's Garage" somewhere to the west. Just continue on the main story quest and you'll get there eventually.
around the level 10 or so, you can travel to megaton or vault 101 and you will trigger a distress call, then it will add the quest
Yes, it is possible to gain access back into Vault 101 on Fallout 3 for Xbox 360. In fact sometime after you escape there is an optional quest where Amada needs your help because "chaos" is happening.
You can hear it after you beat the quest "Project Purity." You will hear a distress signal from the vault and if you listen to it you will get a new quest, "trouble on the homefront" once you walk into the door of the vault you will once again hear the Vault 101 PA system, not that there's much to hear. p.s. you have to be somewhere near the vault such as in Megaton to hear the distress beacon.
If you are looking for this, I'm guessing you're on the quest "Still in the Dark". It is in a locker in Vault 22.
If you are talking about the "Trouble on the Homefront" quest its after you complete Project purity. Travel to a relative distance from 101, Megaton for instance, and you will hear the Vault 101 distress signal on you Radio, listen to it and you will then know what to do. Good luck.
There are 7 vaults as follows: Vault 87 Vault 92 Vault 101 Vault 106 Vault 108 and Vault 112
do the quest agethas song to get the location and passwords for all vaults (exept 101 cos anita changed the password for the quest trouble in the homefront you get this after the waters of life quest just walk neer top 101 and youl pick up the vault 101 emegency brodcast from anita asking you to help her)
vault 77 doesn't exist in the game.
