Axicon — Germany, founded 1998

A crack intro from Axicon, a German group founded in 1998 — well into the C64's second life as a hobbyist platform. Firefox coded the intro, Brainsmasher provided the graphics, and Brizz (Stefan Sebastian) contributed the music with "Braintoolz #2," preserved in the HVSC. The release date is unrecorded on CSDb, though the group's 1998 founding suggests a late-era production. Axicon used the short tag "AXC" and appears to have been a relatively small group with limited documentation across scene archives. No scrolltext or additional historical context has been recovered from Demozoo, Doc Snyder's page, or Freeze64. The intro represents the continued vitality of the German C64 scene even as the platform entered its nostalgic revival phase in the late 1990s.
