I made this base on the island, as it's the biggest area to allow the most pieces in one area. It has one entrance to get into with a narrow corridor that you have to go down. There are balconies on both sides of the corridor which leads to defense towers, which are stacked on top of the balconies to give my NPCs a longer view. Then, when you pass the corridor it leads to a bridge that crosses over the corridor and connects both balconies for easy access, where another NPC is guarding another defensive post on top of the bridge which they can look and see down the corridor for any raiders approaching, where 2 shotgun turrets on both sides. As you pass that, 2 concrete blocks on both sides with staircase in the middle to go up into the main tower. there are 2 defensive outposts on the front of the 2nd level, and 2 defense towers on west and east on first level. As you go through the main entrance of the tower, you can head through the back door which leads to the farming area which I have blocked off as well so raiders cannot enter through the back. The only way to enter through the complex is through the south entrance; there's only 1 entrance to this base. On top of the roof(s) which cover the balconies of the main corridor are 2 missile turrets on both sides, 2 machine gun turrets in the front gate, and 2 security lights. There are 3 levels to the main tower. I placed my little store bazaar outside in the farming area. You take a set of stairs up to get to it, and of course, the only way to get there is to go through the back entrance of the tower.
I'm thinking about putting Lance here.
