@39zapatero ammo stations are usually dependent on how many tanks or lazers you have installed. What I found is if you read under where it says about buying an ammo station it will say something like 1/3 cannons built. So you build 2 more canons and then they become available. I can't recall if it was reliant on canons. For example you need 3 shields built before you can use an air lazer. Then once you have 1 air lazer in you can use ground lazers.
