Ships, take to the skies! [FF/PP]

One player is on a ground base and has an airport, three others are in ships. And the same setup for the other side. There is a relatively low middle pillar. Keep in mind that in order to build smokestacks your core build will have to be in water and for turbines it'll need to be on land. Same goes for mines and propellers. Map is basically symmetrical and very wide. Fortships and Pilotable planes are what I intended this map for, but do what you want. High Seas required obviously. Mods: Astronomical world bounds
