Shadow of Atlantis (also known as Nautilus) is a point and click adventure game that was originally in development for the Sega CD and after many delays, it was ported to the 32X, but in the end it was never released. The project was based on characters and situations from Jules Verne’s classic novels, 20000 Leagues under the Sea and Mysterious Island. Shadow of Atlantis was designed and produced by Eric Quakenbush, a game designer that worked with Sega on many other games, as the cancelled Virtua Hamster. There were even some plans to port Shadow of the Atlantis to the Saturn, but as we can read at Sega16, “Sega eventually scrapped the concept altoghter sometime in 1997”.
Also, in ActionPackedVideo‘s Youtube Channel we can see some more videos from the project. As we can read in one of the descriptions:
This was the result of a skunk-works project that I put together with the Sega Multimedia Lab staff that were idle after we shipped Jurassic Park Sega-CD game. The demo got the game a green light and I was promoted to the producer group but it never shipped. Eventually the salary for all those idle workers was billed to my project so you are looking at about $70,000 worth of demo!
Eric Quakenbush designed and produced this CD adventure game which featured live action sequences as well as many intriguing puzzles.
Unfortunately Sega discontinued the Sega CD platform before production could be completed.
Thanks to Celine for the contribution and to Mekanaizer for the video!
