Location of Vault 88
|Leads to: Better Living Underground|
This quest can be started after reaching level 20, or by passing by the area around Quincy Quarries. The Pip-Boy will then receive a new radio signal at any place in the Commonwealth, called the Vault 88 radio broadcast. After tuning in, the radio will direct the player character to find Vault 88 and open its security lockdown.
The entrance to the Vault can be found in Quincy Quarries, through a door on the lower left side of the area, facing north. There, a small group of raiders are attempting to breach the same door. Clearing them out will allow the player character to contact the source of the broadcast and enter the Vault.
