Vault-Tec Workshop Achievements
Bethesda recently rolled out a new version of the 1.6 update for PC which delivers the three Vault-Tec Workshop achievements/trophies. There are three achievements: Oversight, Better Living Underground, and Vault Dweller.
It won't take much to obtain these. The Overseer achievement requires you to, surprise, become the Overseer of the vault.
Better Living Underground is awared to those that unlock all of the build areas of Vault 88, the vault featured in Vault-Tec Workshop.
And finally, you'll earn Vault Dweller when you equip a Vault 88 suit and Pip-Boy on a settler in your vault. Pretty basic.
