The SWWAS series simulates World War II naval combat using a dual operational/tactical system with the following characteristics: The game provides highly abstracted statistics on the various counters for the following: For ships: For air units: Each game is played on an operational map divided into a grid of squares, each representing a 36-mile-wide area.
Players plot their unit's moves, and track damage and fuel consumption, on separate data sheets for their associated fleets.
When units come within range of each other, their gunnery and other factors are translated into numbers of dice rolled to attempt to hit enemy targets.
Hits, especially those which penetrate armour, will gradually erode the ability of a ship to fight, and ultimately can sink it.
Bomb Alley was the fourth game and according to Avalanche Press, "the most ambitious" (although that title would only last until Leyte Gulf was released).
Strike South covers Japanese operations in 1941 and early 1942, including the invasions of Malaya, the Philippines, and the Dutch East Indies (Indonesia).
Bismarck is the first game in this series set in the Atlantic Ocean and covers the operations of German commerce raiders from 1939 to 1941.
The game includes the German battleships Bismarck, Tirpitz, Scharnhorst, and Gneisenau as well as the aircraft carriers Graf Zeppelin (as well as her never-completed sister Peter Strasser).
It uses a small box size and comes with a new edition of the series rules and shares a sheet of counters with Pacific Crossroads.
East of Suez was released in early 2007 and featured the British Pacific fleet in both real and fictional operations in 1944 and 1945.
Strait of Magellan was a scenario-only supplement featuring 10 scenarios introducing the major powers onto the Cone of Fire maps.

The Tsar's Navy was one of a series of alternate history products originally offered by download, with counters to be printed and produced at home.
Spice Islands was one of a series of alternate history products originally offered by download, with counters to be printed and produced at home.
Effectively a second edition of Spice Islands, this abandoned the prior supplement's background for that of the Second Great War, with the development of the Dutch navy handled in a similar fashion to that of the Austro-Hungarian and Imperial German fleets.
The supplement expands the Argentinian, Brazilian and Chilean fleets from Cone of Fire to fit into the Second Great War background.
