History

Released
30 May 1988
Group
The Softkiller-Crew — Austria, founded 17 February 1987

This Softkiller-Crew intro uses Rob Hubbard's "Thrust" as its ripped soundtrack — Hubbard being the single most-ripped composer in the entire C64 cracking scene. CSDb catalogues six TSK crack intros spanning from August 1987 to May 1988, with this May 1988 release among the latest in the series. The Softkiller-Crew was an Austrian group founded on 17 February 1987, with key members including Antitrack as coder and cracker, Softguru handling code and graphics, and The Soft Killer serving as cracker and organizer. The group dissolved in 1988 after roughly a year and a half of activity. Austria's C64 scene was smaller than those of neighbouring Germany or Scandinavia, making TSK one of the more notable Austrian cracking operations of the late 1980s. This intro was reused across several game cracks including Cybernoid, Hercules, Soko-Ban, and The Flintstones.
