The Vault-Tec Workshop DLC for Fallout 4 is now available on all platforms. The add-on lets players built their very own nuclear bomb shelters, filling them with pre-war furniture, lighting and other stuff, using tools similar to those that you build your settlement with.
Once your vault is up and running, you can fill it with people and then run experiments on them.
The pack costs $4.99 (or equivalent) and is also included in the Fallout 4 season pass. It's out now on PC, PlayStation 4 and Xbox One.
