Victory at Sea is a simulation of World War II at sea. It combines War at Sea (second edition) and Victory in the Pacific, although it is advisable to use War at Sea 2 since Victory at Sea uses several maps included with this game.

WAR AT SEA and VICTORY IN THE PACIFIC use the same game system to recreate the naval wars in the Atlantic and Pacific during World War II. The temptation to link them into one game about the worldwide WW2 naval struggle has resulted in this global scale game appropriately named VICTORY AT SEA.

Both games are played simultaneously. The first two turns of WAR AT SEA will be played before the start of VICTORY IN THE PACIFIC; thereafter the two games will be played simultaneously, with turn 1 of VITP being played at the same time as turn 3 of WAS, turn 2 of VITP at the same time as turn 4 of WAS, and so on. So that both games will end on the same turn, two turns are added to the end of WAR AT SEA, so WAR AT SEA becomes a 10-turn game. For simplicity’s sake the WAR AT SEA turn numbering system will be used to identify turns in the combined game—so VITP starts on turn 3.

Note that this variant is not a complete game. Ownership of both of Avalon Hill's Games VICTORY IN THE PACIFIC and WAR AT SEA & (recommended) Variant WAR AT SEA II (or the Counter-Moves WAR AT SEA DEUX Variant) are required for VICTORY AT SEA.
