Concept: Spies

[Garett20]

I have a couple new ideas for a spy unit. What if the spy operated like an air unit? Missions would be destroying improvements, and destroying buildings. You could also set them to intercept, to stop enemy spies. You could also use a counter intelligence unit which would be like an A-A gun. I think it would have to be done in the dll, but I'm not sure.Could this be done with lua?
