Konpeki no Kantai

The game follows all combat operations depicted in the anime series of the same name, with battles fought on an isometric map. The player also has the capability to develop new weapons. However, where the anime series ends with Japan declaring victory with the US and Britain over Nazi Germany, Japan's survival in the war is uncertain when Otaka's government is deposed in another coup, Yamamoto dies in jail, and the Deep Blue Fleet's secrets are exposed.
