Instructions for "Artillery Duel" from "Arcadian:"

"Artillery Duel" is an intriguing game by John Perkins. The machine sets up a 
random ground and adds two gun emplacements. As each player's turn is taken, he 
adjusts the knob for barrel elevation, moves the joystick to add or reduce the 
number of powder bags (by whole bags, sideways; by tenths, back and forth). 
Then when ready, pull the trigger. There is gravity and a random wind. Anyway, 
the gun recoils and there goes the shell. There is an explosion when it lands. 
A gun is destroyed when less than half a gun remains (the repair crew can 
replace a gun barrel). The program uses all available space- don't enter lines 
3 & 4. Be sure to exercise the joystick to see how the variables work.


Reprints and Re-Issues of "Artillery Duel:"

"Artillery Duel" is such an outstanding game that Astrocade, Inc. reprinted it 
in the "AstroBASIC" manual (this is the manual that comes with the BASIC 
cartridge that includes the build-in interface).  Both editions of the 
AstroBASIC manual's re-printing had errors which were corrected in the 
"Arcadian newsletter:"

Instructions for "Artillery Duel" from the AstroBASIC manual:

Artillery Duel is an intriguing game submitted courtesy of "The Arcadian," a 
monthly newsletter serving the Bally BASIC programming hobbyist and published 
by Bob Fabris. This program sets up a random mountain scene and adds two gun 
emplacements. As each player's turn is taken, he adjusts the knob for barrel 
elevation, moves the joystick to add or reduce the number of gunpowder bags (by 
whole bags sideways; by tenths back and forth). Then when ready, pull the 
trigger. There is gravity and a random wind. The gun recoils and fires the 
shell. There is an explosion when it lands. A gun is destroyed when less than 
half a gun remains (the repair crew can replace a gun barrel). The program uses 
all available space, so don't enter lines 3 and 4. Be sure to exercise the 
joystick to see how the variables work.



Archive Notes:

This "Arcadian" program was found in Ken Lill's tape collection.  Paul 
initially added back in lines 3 and 4, which are comments with the program name 
and author, but then the game runs out of memory.
