War at Sea is a simple strategic wargame covering the Battle of the Atlantic and naval warfare of the Mediterranean in WW2.The game divides the Atlantic into 6 sea areas. Each turn the players move their ships from port countries to one of the areas.After all ships have been moved, a battle occurs. After a number of rounds, until one side or the other retreats or loses all of his ships, the player with ships left takes control of the area and a scores a number of 'Points of Control'. (Exception: German U-boats only have to survive one round anti-submarine combat and may stay in the area, even if the area has Allied ships. The Allies cannot score if a U-Boat occupies the area.)Additional points are also earned for convoys successfully crossing the Atlantic to England or Russia (for a BIG three POC).Variants: There was an expansion available called War at Sea 2 which added more ships, a larger map, and modified rules. The WAR AT SEA 2 game components included in the Expansion: 22' x 24' unmounted mapboard (replaces the original board) 1 Counter sheet (adds more ships to the original counters) 3 Player aid cards -- Two Allied OBs -- One Axis OB 1 Rulebook (replaces the original rulebook)Avalon Hill Complexity rating - 1 - BoardGameGeek
