The pen-and-paper game Battleship gets another digital translation, which pits man against machine for a round of grid-based marine warfare. Both sides get five ships each - of varying sizes - and hide them within their respective game boards, invisible to the opponent. Each side then proceeds to fire in turn, by selecting a target grid position. When all the squares occupied by a ship are hit, it is sunk; the first player to destroy the entire enemy fleet will rule the waves.
