If you don't have an atariage account, go to the attached thumbnail part of this post. The thumb nail has one of the 5 screen shoots. The rest are too big for posting in terms of memory.
The 2nd post by Jetboot back on that page has the pictures of electrop 7800 artwork with it being levels mocked up thanks to Amy Hennig providing the copies of the artwork. The game was supposed to be a Robocop type side scroller.
Amy Hennig did the art for the game and she said " I don't think there's an existing copy of the game out there, unless the programmer kept one (neither of us worked for Atari; we were both contractors). The game was finished, btw, I think it was just so late in the 7800's life that Atari decided not to publish it. Too bad -- I think it was a pretty good game, for its time."
The artwork I saw on the post looked like Electrocop borrowed alot from nes games.
