Sea Battle is a strategic game for two players only. Each player controls a fleet of ships including Submarines, Destroyers, and Battleships. The goal is to engage and sink enemy ships. The winner is the player who commands the troop transport ship into the opponent's harbor.
The game has two phases: the strategy phase and the combat phase. In the strategy phase, you need to maneuver your fleet into different strategic positions on the map, lay mines, and repair fleets. Opponents engage in ship-to-ship warfare in the combat phase, triggered by the ENGAGE button.
