Deep Scanner (ディープスキャナー) is a cancelled run & gun / action game that was in development by Sammy for Mega Drive. A single screenshot was published in french magazine Joypad (issue 18, March 1993) with a short description:
“[…] an action game with multi-directional scrolling. Developed by Sammy, Deep Scanner may well contend more than one, given the quality of the graphics and the various difficulties encountered during this game. Armed with a laser gun and other weapons you may find during your peripeties through bonus areas, halfway between Rolling Thunder and Double Dragon, Deep Scanner will allow you to freely choose between a half-dozen of levels, each ending with a final boss monster. […] you have to be quick because time is limited and enemies do not wait to jump on you.”
More images and details could be still hidden away in other Japanese magazines.
