simulates the arcade classic with the cities and the stuff
shooting down from the sky and stuff. The computer plays against itself,
desperately defending the forces of good against those thingies raining down.
Bonus cities are awarded at ever-increasing intervals. Every five levels
appears a bonus round. The computer player gets progressively more intelligent
as the game progresses. Better aim, more economical with ammo, and better
target selection. Points are in the bottom right, and high score is in the
bottom left. Start with -smart to have the computer player skip the learning

The layout of the screen isn't quite the same as the game this program tries to
emulate. In this this program, the missiles come out of the cities; when
really, there are supposed to be three missile bases on hills, with the cities
in the valleys between them.
