Konpeki no Kantai is based on the anime series Deep Blue Fleet , which, in its turn, is based on the novel of the same name by Yoshio Aramaki. The game follows the story of the anime since the first episode. It is set in an alternate universe, following a fictional story of a real historical character, admiral Isoroku Yamamoto, who becomes a key figure in shaping Japan's future.
The game re-creates the battles against the USA during World War II, as depicted in the anime. It is a turn-based strategy game with heavy emphasis on naval combat. As the commander of the Japanese Deep Blue Fleet, you can control every aspect of your fleet, including customizing warships, assigning soldiers, and creating new weapons to be deployed in battles.
Konpeki no Kantai was released for the 3DO console on 1995 .
