IL-2 Cliffs of Dover Add-on in September? is now accepting preorders of an add-on for IL-2 Sturmovik Cliffs of Dover which appears to carry the title Cliffs of Dover - Aces! Helmut Wick vs. J.C. Dundas - Deadly Duel in November 1940, or something to that effect. Translating the page offers extensive details on new campaigns and features in this expansion for the World War II combat flight simulator, which appears to carry a September 1, 2011 release date.
