There should be a way in survival, to pick the country of the enemy side, and there should be allies there too. You should be able to pick the side of the allies, how much you want, and there could be a mix of countries against you, and for you in the same game. It's really annoying when you fly too high, and a message comes up and says "return to battlefield", so please raise the sky limit. And what about a campaign? Please give AP points for destroying buildings. Make it so that you can land on runways without dying. + if you want these things to happen!
I think there should be a way to assist friendly compounds directly like if they are being attacked, you could send some of your survivors to help them. More friendliness in this game would be nice.
