History

Released
c. 2000s-2010s
Group
Laxity (LXT) — Germany, founded 1991

This is the forty-third crack intro from Laxity, the German cracking group founded in 1991 by Mister Magic under the motto "The Right Way To Go!" The high intro number reflects the group's extraordinary longevity and output — their numbered series eventually exceeded 139 entries, making Laxity one of the most prolific crack intro producers in C64 history. Doc Snyder's page documents Didi as the group's primary coder, with DanDee, Freeze, and Shine contributing graphics, and musicians including Response, SMC, Apollyon, Gaunt, Jammer, and Klegg providing soundtracks. CSDb lists the group's active roster as DanDee, Didi, Durchspieler, Goat, KBS, and O'Dog. The Atlantis Prophecy archive preserves an interview with the group. Scrolltexts from Doc Snyder's page show Laxity greeting Onslaught, Excess, Triad, Nostalgia, Fairlight, Genesis Project, and Quantum. This is one of three Laxity entries in the rankings — see also LXT-13 and LXT-20.
