Better Living Underground

Better Living Underground is a quest in the Fallout 4 add-on Vault-Tec Workshop.

Detailed walkthrough
Upon entering the vault using your Pip-boy's connection interface with the vault door, a voice will talk to you via a broadcast system. To enter the main part of the vault, you must shut down the security lockdown and then access the workshop. A number of feral ghouls populate the area.

To the right of the vault door is the security office, containing the terminal needed to lift the lockdown. It does not require hacking to use. Once the lockdown is lifted, the alarms will shut off and the workshop can be used once its conrol board is put in place. To the left of the vault door is a computer room containing Andersen, who is in possession of the Vault-Tec control board needed to unlock the workshop.

Once the workshop is restored, you can use it to clear the debris piled up in the stairwell, where you will be greeted by Valery Barstow, the proposed Overseer of the Vault.
