Group
Eagle Soft Incorporated — Canada, founded 1982

Ranked #18 on intros.c64.org, this is the lower-numbered counterpart to #1 ESI: both intros share the same CSDb release "Eagle Soft Incorporated Intro (Eagle 2x1)," rated 9.75/10 and dated 15 July 1987. Mitch — real name Mitch Solomon per Doc Snyder's page — coded the intro, Scorpio painted the eagle bitmap, and the soundtrack is a medley of six ripped tunes: "R1-D1 Unit Attack" and "Zig Zag" by Antony Crowther, and "Footballer of the Year," "Future Knight," "Mountie Mick's Death Ride" and "Bulldog" by Ben Daglish. A 2023 comment on Doc Snyder's page from Jazzcat notes that ESI had two female graphicians — Ladyhawk of TSC painted the earlier 1986 eagle, and Scorpio painted the one used through 1987 and 1988 that appears here. The scrolltext sends greetings to NEPA, The Alliance, Triad, TTI, Hotline and Fairlight and closes with the line "esi #1 / rush #1 / soho #1."
