Next up is Nuka World in August
Vault-Tec Workshop, the fourth Fallout 4 DLC and part of the Season Pass, will be released on July 26, 2016 for $4.99. It’s basically a miniature version of Shelter housed within Fallout 4, allowing players to build a vault and adjust inhabitants accordingly as the Overseer.
It goes without saying that you should be cautious of any add-ons for this game, but you can watch some footage of Vault-Tec here if you need a nudge in either direction. The stream even starts off discovering the DLC for the full experience.
