Your chains being the only thing you have to lose aside, the trailer goes into depth about using the mobile assembly stations, camps. The extent to which these can be used is unclear, but seemingly your home works on the basis of a template you can update and set it up anew every time you lose it one way or another.
Additionally, you can pool your resources together and work with other wanderers in glorious cooperation to build your camps together, interlocking like those pirate ships in the third Pirates of the Caribbean movie. Shame you can’t build a settlement that would actually move on its own. I like moving cities, it’s a cool visual.
In any case, still no info on how these camps are supposed to fare against nuclear launches, but given the trailer, probably poorly.
