At the bottom of the first and last page, there is a hand-written copyright to an illustrator "Sétantae" who has a few comic book credits around 1992-1993. No other reference to this creator anywhere else. On the other hand, the title page expressly attributes all material to Scott Harrison and Gary Peterson.
"Part Three" likely references the two issues of Brainstorm's short-lived "Intrazone" series.
