Strategic Command World War I: The Great War 1914-1918—whew!—received a substantial update today. Patch 1.02 includes not only a new Forced March option, “more realistic” Submarine Combat Model, and “new and improved” Research system, but an entirely new WWII-based campaign: 1939 Storm over Europe.
Additional patch details can be found on the official download page. Note, though, that saves with prior versions are not compatible with this patch.
