The Great War Revamped Rule Book (2019)
1918 saw great changes in the warfare of the Western Front. Russia pulled out of the war, freeing thousands more German troops to push the Allies back huge distances. The Allied counteroffensives, with the new tanks, evolving tactics, and the arrival of the Americans, forced the Germans back towards their own borders and defeat.
Last year Battlefront marked the centenary of the start of World War One by releasing a set of rules for British and German forces, with issue #324 of Wargames Illustrated. Now those rules have been expanded to a 72-page book, including the Americans and French.
