If you didn't know, the maximum allowable defense buildings you can have of the same type is 50. The max for money buildings is 2.
Right now i have 50 Gatling Guns and can't build any more.
So...Whats next?
Do i just build Machine Guns (and not level them)?
I'm level 93 so i can't build / nor afford the 500,000 air to ground missile launchers (or w/e they are)
