Sewer Shark is a first-person rail shooter game, the first video game for a game console to use full-motion video for its primary gameplay. It was originally slated to be the flagship product in Hasbro's NEMO video game system, which would use VHS tapes as its medium. However, Hasbro cancelled the NEMO, and Digital Pictures later picked up the game for the Sega CD system. Sewer Shark was one of the first games to come out for the Sega CD - shortly after its release in 1992, Sega began to include a copy of this game with each Sega CD unit, making it one of the most widespread games for the system. It was later ported and released for the 3DO in 1994. [source:wikipedia]
