| 22 | .SH DESCRIPTION |
|---|
| 23 | .PP |
|---|
| 24 | \fIPenetrate\fP simulates the arcade classic with the cities and the stuff |
|---|
| 25 | shooting down from the sky and stuff. The computer plays against itself, |
|---|
| 26 | desperately defending the forces of good against those thingies raining |
|---|
| 27 | down. Bonus cities are awarded at ever-increasing intervals. Every five |
|---|
| 28 | levels appears a bonus round. The computer player gets progressively |
|---|
| 29 | more intelligent as the game progresses. Better aim, more economical with |
|---|
| 30 | ammo, and better target selection. Points are in the bottom right, and |
|---|
| 31 | high score is in the bottom left. Start with -smart to have the computer |
|---|
| 32 | player skip the learning process. |

|---|
| 79 | The layout of the screen isn't quite the same as the game this program |
|---|
| 80 | tries to emulate. In this this program, the missles come out of the |
|---|
| 81 | cities; when really, there are supposed to be three missile bases on |
|---|
| 82 | hills, with the cities in the valleys between them. |
