History

Group
Venom — Denmark, founded 1987

A crack intro from Venom, a Danish cracking and demo group founded in 1987 by Rebel. CSDb documents three members: Rebel (mega swapper), Tintin (coder and cracker), and Vision 2016 (cracker). Despite the compact roster, the group produced 23 releases — predominantly game cracks from 1987 including titles like Airwolf II, Cyborg, and Nemesis the Warlock. Venom also released standalone intros and a one-file demo called "The Wild Side." The group operated during the formative years of the Danish C64 scene, which would soon become one of Europe's most productive — home to Dominators, Triad, and numerous other crews. The group's name was not unique in the scene — separate formations called Venom existed in the United States and Germany, necessitating the "(DK)" suffix used on intros.c64.org. No individual credits for this specific intro have been identified. Comments from Bug Guts and Rough on intros.c64.org confirm the production's recognition within the preservation community.
