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

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