The Nukebusters — New Zealand, founded 1985

The Nukebusters Intro #1, released in October 1987, is a crack intro from The Nukebusters -- a rare example of a C64 cracking group hailing from New Zealand. The group was founded in 1985, and this intro's full CSDb title -- "The Nukebusters Stop This Insane Arms Race Intro" -- reflects the Cold War-era anxieties that occasionally surfaced in scene productions. Graphics are credited to Tony F., though no coder or musician has been identified for this release. The intro has drawn nostalgic community comments, including from a former member identifying as rObin, who went on to join Shining 8 and later Tristar. The Nukebusters' geographic isolation -- far from the European and North American hubs of C64 cracking -- makes their documented presence in the global trading network all the more notable.
