You could choose which buildings you want to add them to, kind of like adding a turret to them. They could be rearmable, like mines. It would be interesting, especially if an attacker couldn't tell which buildings had the extra guns before deploying troops. All the sudden a gun pops out of a window and starts sniping gunners. They could either be mechanical guns, to be rearmed, or maybe pirate mercenaries you can hire and place in buildings, that you could choose between a couple different types, and they have to be recruited. Either way it would be a fun addition to defenses.
You just gave me an idea. How about some quicksand? Watching the attackers get swallowed up would be cool.
That sounds like a new kind of fun trap Finally there is a trap we can hide on our beaches. Rather than a green mine showing up like a dead giveaway
It would be a neat way to snipe a gunner thrown over there (although technically you could do it with a bomb and some decorations, it'd be more covert than that in theory But then you'd be sacrificing a defense that could otherwise be in your main base. Pros/cons of different strategies. Another dynamic to play with when building.
