Something with an above ground elevator down to a 2-4 story underground base with multiple levels that can be built within however you see fit. But I'm looking for almost an exact replica of the Lost Hills Bunker from Fallout 1. Sure homemaker has added some bunker additions, etc. It's extraordinarily difficult to make any bunkers in the style of the Brotherhood of Steel from Fallout 1, Fallout 2, Fallout: Tactics and Fallout: New Vegas with the limitations of the spawn menu. I think this is a must-have mod, and I'm kinda shocked no one has made it yet to be honest.
