Galaxy Force's sole catalogued intro dates from 1988 and was coded by Metal, identified by Doc Snyder's page as Torben Korgaard Hansen, a member of TBI who contributed his programming skills to the group. The SID tune "Swapper Zax" was composed by Fate, the handle of Peter Slotta, and is preserved in the High Voltage SID Collection. Galaxy Force was a German group based in the Oberhausen area, and the scrolltext reveals a youthful, enthusiastic crew whose members included Zak, Pegasus, and The Sys. The intro accompanied a crack of "Chuck Yeager's Advanced Flight Trainer" from Electronic Arts, with Zak boasting the game was broken in a single day. Greetings in the scrolltext reach out to International Cracking Company, Horizon, X-Ample, and The Blasters Inc., placing Galaxy Force within the broader German cracking network of the late 1980s. The group's output appears limited to this single documented intro, suggesting a short-lived but spirited operation.
