Dark Horse Insider Vol. 1 No. 19 -- ALIENS: COUNTDOWN chapter six (1991)

DARK HORSE INSIDER #19 -- "ALIENS: COUNTDOWN" (chapter six)

The first incarnation of Dark Horse Insider was a free (it was sold in bundles of 100 copies for $5 to retailers) eight-page, monthly "newspaper" published by Dark Horse Comics from 1989 to 1991 (in the style of Comic Shop News). Starting with #14 (Sept. 1990), the strip ALIENS: COUNTDOWN by Mike Richardson and art by Denis Beauvais ran for 14 one-page installments until the penultimate issue #27 (Nov. 1991).

"Aliens: Countdown" was only reprinted one time to date, as a two-part insert comic included with #9-10 of Dark Horse International's Aliens Vol. 2, and thus became quite rare. The final issue #28 (Dec. 1991) contained a two-page preview of the next strip, an Aliens vs. Predator story that would start in Vol. 2 of the publication.
