I had this idea a few days ago, and tested it. i placed the brain module in thin air, not far from the ground, and placed the bunker modules around it. the end result was a a battleship-like structure. and the best part is that the AI can still attack the base. i spent a solid 2 hours fighting off boarding parties. just wanted to get the idea out, because i also had this idea: what if the floating battleship was able to react to physics? Epic crashing and battles ensue!
also, sry for posting this in the wrong area the first time, was not sure where to post it
