Bethesda announced at E3 2016 that it is releasing a bunch of new DLC for Fallout 4 later this year. You can create a lot of cool new things in the game.
First there is a Contraptions Workshop in Fallout 4. This new add-on allows you to add conveyor belts and other cool things like you will see in a factory. The Contraptions DLC will be released next week.
The other DLC coming to the game is a Vault creator. This is where you can create your own Vault much like the other shelters that Bethesda has already made in the full game. This workshop is due out in July 2016 and looks like it could be a lot if fun.
Bethesda has a lot of other things in store at E3 2016, so stick around and see lots of the other things that have been announced.
