Publisher: S.S.

S.S. is the name the site lists as the publisher of Pyramid War, an unlicensed cartridge from the early 1980s. The game is Activision’s Chopper Command with new graphics and a new story: you fly a propeller plane over the desert and protect a column of tanks from enemy helicopters and jets. The cartridge was sold by labels such as Suntek and Rainbow Vision, and AtariMania dates both to 1983.
