Hotline [HTL] -- Netherlands, founded August 1986

Hotline Crack Intro #02 -- catalogued on CSDb as "Hotline Intro 13" -- is a C64 crack intro released on 10 September 1987 by the Dutch cracking group Hotline. CSDb credits Softhunter as the sole coder, with no music or graphics listed. Doc Snyder's page also lists Softhunter among Hotline's coders. The lack of music credits is consistent with an early production from this period, before the group secured contributions from prominent SID composers like Jeroen Tel and EVS. Hotline was founded in August 1986 in the Netherlands and operated under the tagline "Where cracking is an Art." The group built an extensive catalogue of numbered intros documented on Doc Snyder's page, with coders including The Silver Surfer, BOD, The Mercenary Cracker, and Coco alongside Softhunter. The release is preserved on CSDb as release #53455, verified through the Doc Snyder link.
