NAME

penetrate - simulates a classic arcade shooting game  

SYNOPSIS

penetrate [-display host:display.screen] [-root] [-window] [-install] [-noinstall] [-visual visual] [-bgrowth microseconds] [-lrate number] [-smart number]  

DESCRIPTION

Penetrate 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 process.

BUGS

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.
