Sea Battle is a Battleship variant: Two players spread ships of different sizes on a squared game field. Each turn you guess a coordinate, destroying any enemy ship part located there, before they return fire, with a player eliminated on losing all ships totally.
This standard game can be played on three sizes of board, or the variant Battle Mode has players select which type of ships they would like as part of their fleet before placing them, each having different weaponry to attack the opponent in varied ways. Super Battle Mode includes graphics of attacks taking place.
Features multiplayer either through pass-and-play or with another console through Game Link, as well as singleplayer fights against the CPU.
