Basically, I would like to see each Bunker become its own Build-able place. The Current Storage box would be there and act as normal, But each Bunker would get its own separate storage that can only be accessed in that bunker. As for build-able items, you could make the crafting stations, add Storage rooms, maybe even trophy rooms (display parts of killed enemies) and Display Rooms (for weapons). The total amount of room available should be limited.
Now for the fun stuff. Schematics to build for your own robotic guard dogs and a workshop to build them (only in the larger areas of a bunker.) you could build any guard dog style (proto, finx, etc.) with any weapons. tho you will lose the weapon in creation. These dogs only guard the bunker they are in and never leave, so they cannot help with anything outside the bunker.
1.If they do add a true survival mode that had food and water rationing and maybe even weather that affects your health, then add build-able or usable kitchens for food crafting and closets to hold outfits.
2. If NPC’s are added then guard rooms, and sleeping quarters could be added. maybe even a trading post.
Any other thoughts to add?
