- Mayhem — United States, founded 1986
The tenth numbered intro from Mayhem, the American cracking and importing group founded in 1986 and dissolved in March 1989. According to CSDb, the group's founding members included Sonny, Diver One, and Double D, though none can be attributed to this specific production. The group maintained a large roster of approximately 45 members spanning crackers, coders, importers, and sysops. This intro attracted comments on intros.c64.org from Changeling of Abyss, Zyron, and Hades — the latter two being recognised scene archivists. Mayhem's dissolution came when key members left for commercial work, with the remnant joining Exodus. The "(US)" suffix distinguishes the group from the British Mayhem (ID 582 on CSDb). All five Mayhem (US) entries in this collection — including #493 Mayhem (US)-02, #487 Mayhem (US)-04, and #472 Mayhem (US)-06 — lack per-intro credits on CSDb.
