This is the thirty-eighth crack intro from Mayhem, a British cracking and graphics group distinguished by the "(UK)" designation from the American group of the same name. CSDb catalogues the group under ID 582, with over 1,000 releases spanning from 1993 to 2004. Key members included Met (cover designer, cracker, graphician, organizer), Hellraiser (coder, cracker), Joker (coder, cracker), Primus (coder, cracker, founder), and Motion (coder, graphician), who also worked with Cosine. Doc Snyder's page documents two Mayhem (UK) productions — a cooperation with The Ancient Temple coded by Case with music by Guy Shavitt, and a crack intro using Laxity's "Ikari Intro" tune. A separate CSDb entry for a 1995 Mayhem release titled "Reflect Intro" credits Motion for code and graphics, with music by Drax performing "Drudgery." The high intro number confirms the group's prolific output. This is one of two Mayhem (UK) entries in the rankings — see also Mayhem UK-04.
