Usually i build them 5-6 stories, with a wooden gate, then 2-3 metal doors, and then multiple fake rooms with metal doors on each story, and each staircase is double doored, as well as usually their is an entire building attached that is all fake aswell
Sounds good... How wide are they? When we build bases we build about 20x20 and 10 stories high with strais on different locations on each floor forcing you to go through allot of doors between each floor. Then have a 5-6 foundation thick maze surrounding the building that can't be exit on the ground floor preventing any one to be able to come in by building a "sige tower".
