Could someone make a map, ever see "the abyss"?

well a map like that, I don't kno if its possible but could have a underwater map. Little station like in the movie under water with a cliff edge that once you fall off of and down around 20 feet you die. Have 0 light just the lighting from the station. and maybe things where you close a door and you can then flood a room. And if this keeps going with could have mini subs with the help of scorpio midget's file for planes but have a mini instead.

anyone?
