1) missile turrets for vertibirds attacks
2) turrets throughout the whole place to prevent : a) infiltrated men with stealth boys b] Underground attacks
3) solid structures that can withstand an artillery attack
4) fat man.
What settlement (or any place ) can stand against this kind of weapon ? It's possible?
5) Wall of Covenants is enough or the castle walls are the minimum ?
Thanks sorry for the English mistakes. I'm drunk.
