Which Fallout 76 lead Jeff Gardiner said in a recent QuakeCon at Home Q&A stream are instanced sections for C.A.M.P. builders to create larger spaces. Ala the Vault construction seen in Fallout 4 - where access to a larger space and capacity led to some truly impressive creations. .

In the session Jeff noted that the team is working on improving the building to add more capacity and to better streamline and support player bases in Fallout 76. With instanced C.A.M.P. sections being something the team is actively working on.

Something else the team is also working on? Mod support - which is still on the cards. According to Jeff, "we've had to put a lot of resources into that". Adding, "it's not just drag-and-drop from the previous games because of the way our client-server architecture works".

As a Bethesda joint there are ways to mod Fallout 76 currently being employed by users on private servers - though that's a far cry from official support that will no doubt come to Steam with more robust management and Creation Kit tools.
