'Special Force Girls' is the same game as Bally Midway's 1986 'Special Force' but with a different backglass. Dennis Nordman said Bally Wulff imported this game from the USA and put their own backglass on it because the USA backglass art was deemed too military. The artist of this backglass is Mychael Gerstenberger from Berlin. He told us that the backglass design was printed at Bally Wulff's own screen printing department in Berlin, and then assembled into the original U.S. machines in Berlin. This game uses the 68000-based "Sounds Deluxe" sound board.
