This is just an Idea but what about we have underground caves in PA? that way we could 'hide' troops in them and when an enemy comes by you take them out and attack. Also another idea is that we have special robots. For instance some can go invisible for a certain amount of time, some could bury themselves and come out when someone walks by, or some shoot fire and melt the enemies. Just curious about these ideas. My final idea is that we have buildings that we can hide/fortress units (much like Red alert 3). That would mean that if you are being over run, you could hide in a building or something.
