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.
