Navy Blue — About this game
``Naval Battle Game Navy Blue'' is a game in which you place your fleet in a grid of sea areas and take turns specifying attack points to search for your opponent. Even if you miss your target, if there is an enemy ship nearby, you will be notified that it is on fire, so you can narrow down the location by combining reactions instead of just guessing. The ships and weapons that can be used are determined by commands, and after selecting special weapons for each ship within the limits, deploy your own troops. It is also important to consider how to use equipment that searches a wide area and equipment that sinks the ships that are found. If you hit all the squares of the enemy ship and sink it, annihilating the fleet, you will win. The battle continues from the base to the enemy's base in the upper right corner, and if you break through the surface, you can leave your progress with a password. The Famicom version is for one person against the computer.
