Fallout 4 can now download the latest add-on content.
The Vault-Tec Workshop is now available on PC, PlayStation 4 and Xbox One worldwide.
As previously reported, players can build their very own Vault and attract new Dwellers using pre-war industrial kits.
Vaults can be decorated with furniture, lighting, art and other aesthetics.
As an Overseer, players can run experiments on Vault Dwellers to learn "what makes an ideal citizen."
Fallout 4's Vault-Rec workshop comes with the Season Pass or can purchased individually for $4.99/£3.99
