The Alaskan Cracking Service — one of the more geographically distinctive group names in the American C64 scene — produced this intro released on 5 May 1990. Deathangel's Shadow coded the intro while the music uses Antony Crowther's "R1-D1 Unit Attack," a composition from the prolific British game developer and musician whose work is preserved in the HVSC. Crowther was primarily known as a commercial game developer rather than a scene musician, making this a case of borrowed game music repurposed for a crack intro. Little documentation exists for the group beyond this CSDb entry — no Doc Snyder page, Demozoo listing, or Freeze64 coverage has been found. The group's full name, "The Alaskan Cracking Service," follows the common American naming pattern of "[Location] Cracking Service" seen in groups like Cleveland Cracking Service and Italian Cracking Service. The lack of a founding date on CSDb and minimal online footprint suggest a relatively short-lived operation.
