Hi there,
I feel in terms of furniture for bases can be explored. What I can only suggest is from my thoughts are the following:
-Functional gun racks that can be pick up and placed on the ground or attached to walls (if possible)
-Tables, chairs.
-Signs (boards of some sort that players can write text)
-Sleeping bags (addition storage)
-Electric powered Code locks of some sort.
-And any other interactive cosmetics.
This will give players opportunities to have a more tailored personalised base that will give them a unique experience on Console.
