Screenshots published with a review of the game by the Online Gaming Review (OGR) magazine on 6 January 1997: http://www.ogr.com/reviews/eradicator.shtml (page archived by the Wayback Machine). The screenshots were originally found at Accolade's website, but the Wayback Machine only preserved thumbnails on that page. OGR is known to have used official screenshots in its reviews at the time.
Images found in the electronic product catalog on the Deadlock II: Shrine Wars CD.
