Dear Bob:

Here are two programs for the Arcadian.  Number one is Invisible War, number 
two is Starfighter.  These are both space-type games.  There have been a lot of 
these in the past, they are still very popular.  Also, I am sending you the 
Checkers II with a few small changes that I believe will add a more 
professional quality to the program.  In your letter of June 12 you talked of 
marketing the Best of the Arcadian.  These programs should be as professional 
as possible within the limits of Bally BASIC.  The FC and BC colors that I used 
somehow seemed more pleasing to the eye over the extended period of time 
involved with this program.  You be the judge.  I hope these changes will help.

Back to the two new programs:

Invisible War is a program to be played by a single person.  You control the 
spaceship on the left, the computer the one on the right.  You are visible only 
when you move up or down the screen or fire a laser blast.  The object of the 
game is to hit the computer's ship more than he hits you.  In order to locate 
the computer ship, you can either fire several blasts of your laser, try to get 
him to fire at you, or move your ship to draw his fire.  When he fires at you, 
shoot back as quickly as possible before he changes his location.  One nice 
thing about this program is the appearance of more colors being on the screen 
then we can actually put there.  You can choose from three levels of difficulty 
and you set the number of your laser blasts.

Starfighter puts you in the cockpit of your own starship.  You must destroy as 
many aliens as possible.  Her score is determined by the number of aliens 
destroyed, as well as the readings in your ship.  For instance, the higher the 
temperature, the lower your score.

I hope you find these programs interesting and useful.
