Unlike other Bally electronic pinball games, their documentation for this game shows the model number only as 1233, not 1233-E. We asked artist Kevin O'Connor to clarify for us if he contributed to any artwork for this game. He replies:The only work I recall doing on Fathom was the design and art for the brochure which we created to look like a page out of a comic book. Greg Freres was the lead artist and I believe handled all the graphics for the game. At a Chicago Pinball Expo 2012 presentation, artist Greg Freres stated that Ward Pemberton�s working title for this game was "Barracuda". Greg wanted to use the name "Deep Threat". Both names were rejected by Bally management. Pictured in this listing are the drawings for the "Deep Threat" backglass art and the "Barracuda" playfield drawing.
