Empire Crack Intro #05 is a May 1991 release from the Canadian cracking group Empire, preserved on CSDb as entry #53571. The intro was coded by The Last Dragon and Booze, with graphics by Necromancer and charset by Gotcha. Music is credited to Thomas Detert and Martin Wheeler, whose SID tracks "Clystron" and "Rebel" respectively are both preserved in the High Voltage SID Collection. Doc Snyder catalogues this as Empire's entry linked to intro #05, with the Doc Snyder page showing Martin Wheeler's music credit. The scrolltext for Empire's related intros references cracks imported from European groups -- a hallmark of the transatlantic trading pipeline that characterized North American crews. Empire was one of the few prominent Canadian groups on the C64, maintaining strong overseas contacts throughout their active years. The release is one of six Empire entries in the intros.c64.org rankings.
