Second World War at Sea series

Second World War at Sea is an operational and tactical wargame series produced by Avalanche Press covering naval combat during the Second World War, beginning with the game SOPAC around 2000. Each title in the series focuses on a distinct theater or campaign of the naval war, letting players command opposing fleets in surface, submarine and air actions using a shared operational and tactical rules system across the line. The series represents one of Avalanche Press's principal historical wargame lines, extending the World War II naval simulation genre across many linked titles rather than a single stand-alone game.
