This crack intro from the German group Action is catalogued on CSDb as release #36779, dated August 1989 — just months after the group's founding in February of that year. Cyco handled both code and artwork, with music by Dutch composer Jeroen Soede using his SID tune "Dull," preserved in the HVSC, and the charset by Flex. The scrolltext includes Action's ranking list — placing 711, DCS, Cosmos, and Dynamix at the top — and notes the intro exceeds 50 blocks when crunched. The text also responds to accusations from rival group Amok, defending Action's cracking abilities and boasting about their "best versions" of New Zealand Story and Rick Dangerous. Doc Snyder's page confirms Cyco as both coder and artist for this specific intro. This is one of three ranked Action intros, alongside the higher-placed #56 Action Intro #3 and #626 Action Intro #1.
