800 Fathoms — About this game
800 Fathoms is an exact registered version in this game family. Mariner guides its submarine past underwater creatures and hostile vessels with both torpedoes and missiles. The route becomes tighter as the surrounding underwater terrain grows into the available space, limiting the room for evasions. A more heavily armed submarine waits at the end of each area, forcing the player to overcome its firepower before entering the next, less forgiving part of the journey. Version-specific changes to characters, stages, timing, difficulty, balance, graphics or hidden content are not inferred where the registration does not document them.
