Orbitting the map perhaps? they could have fixed orbits like actual satellites (Goldeneye style) ...maybe even with EMP weapon? Yes orbiting the map and we could take out 1 or more radars to keep it from becoming to easy. It would have to be timed so you can only use it every (just making up number...

The satellites will only be able to see within a small radius around it.

I believe it is impossible to make it "realistic" because of the inequalities that exist between the nations, in the amount of weapons, population, and the size of the country.

Nice mod!
but Australia needs more cities as the population is not spread out enough and if you hit one city you get like 10 mega kills.

Ok that kills my ideas for a mod. I wanted to add a new unit a spy satellite that you can use to watch your enemy and see nukes.

I am new to moding and have big ideas for a new mod.
Could someone tell me if it is possible to add new units, if so could you give me a brief description of how to do this.

Thanks
