History

Released
26 September 1987
Group
Antitrax — Germany, founded 1987

Antitrax's first intro, released on 26 September 1987 and catalogued on CSDb as "Antitrax 2010 Intro." The group was founded in Germany in 1987, placing them in the heart of the era's most active C64 scene. No individual credits for code, music, or graphics are listed on CSDb, and no Doc Snyder page exists for the group. The "2010" in the CSDb title likely refers to an internal designation rather than a year. As a first numbered intro, this represents the group's earliest known intro production — the foundational release from which subsequent efforts would build. The September 1987 date places it in a transitional period for crack intros, as productions were moving from simple text displays toward more sophisticated presentations with custom music and graphics. Antitrax's abbreviated handle on CSDb is ATX. The intro survives through both CSDb and intros.c64.org, though broader documentation of the group remains sparse.
