We're about to try a similar-sounding base, a modified version of blugold1's in this thread. A hallway with electric fences, jumping obstacles, and dart traps. In sandbox testing, it destroyed a group of 10 demolishers AFK, and we do not plan on playing AFK. We hope that no demolishers reach the base, actually. They and cops will be priority targets for us from the rooftop. The riff-raff can get shredded by the base defenses. Anyhow, if the base survives, but with significant damage I will still consider it a success. It can be rebuilt from scratch in one game day. Maybe two if I have to go mine up 12000 rock for cement.
