Zeppelins includes die-cut-and-mounted playing pieces, but these are special, oversized ones: 2/3-inch by 1-and-1/3-inch large pieces depicting famous airships of Germany, Great Britain, the United States, Italy, Austria-Hungary and France. These are used with the new tactical and operational rules provided; unlike the standard game rules that treat all airships the same, with the Zeppelins module, each airship class has its own range and endurance qualities. New airship-centered scenarios, or modifications of current scenarios, are included for almost all of the Great War at Sea games.
