An early graphical version of the artillery game for personal computers emerged on the Apple II computer platform in 1980. Written in Applesoft BASIC, this variant, also called Artillery, built upon the earlier concepts of the artillery games published in Creative Computing but allowed the players to actually see a simple graphical representation of the tanks, battlefield, and terrain. The Apple II variant also took wind speed into account when calculating the eventual result of the fired shot. Lines on the screen showed the players the paths that previous shots had taken toward their target, allowing players to use visual data when considering future strategy. Similar games were made for home computers such as the Commodore PET by 1981.
