As if to prove there's no idea so good that you can't do it several times over in mostly identical ways, here is the third Battleship-like naval combat game for Game Boy. This one is from Nintendo themselves, which means that it's less offbeat than Use's Battleship/Navy Blue or NTVIC's Power Mission, but it's a lot more polished. And it includes an entirely original secondary sub combat mode, too! Just be sure to play with a friend, because the computer cheats like crazy in this one… as usual.
