Factories are triangles. Cities are circles. Bases are squares. In the center is a more different square with the defcon. Cities are required to supply factories. Factories are required to make new units. Bases are required to launch units.
Fighters target bombers and fighters. Satellites target ICBMs. Bombers and ICBMs target factories, cities, bases, and defcon. Bombers target in that order; ICBMs seem to target randomly.
Game over when defcon is destroyed.
Launching an ICBM requires defcon <= 3. The choice to launch is a bit random at defcon 3 and 2 but they all launch at defcon = 1.
Defcon changes to 4, 3, 2, and 1 if a bombers crosses the circular boundaries (radar?) around the center. You can see this happen when the boundary flashes.
