”— Official description
Vault-Tec Workshop is the fifth add-on, and third workshop add-on for Fallout 4. It triggers automatically once level 20 is reached and the player character is outside the Institute. It will also trigger if you travel to Quincy Quarries, which is south of Jamaica Plains.
The following is based on unverified behind the scenes information and has not been confirmed by canon sources.
This add-on bears a number of similarities to the mobile game Fallout Shelter, such as constructing a vault and maintaining a community within it. Vault dwellers in the DLC will also occasionally say lines that previously appeared in Fallout Shelter, such as, "Who do you think would win in a fight, a lumberjack with tentacle arms or a shark riding a unicycle?"
