IL-2 Sturmovik: Cliffs of Dover is a World War II combat flight simulator released in 2011. It was originally developed by the Russian software house 1C:Maddox Games but since 2012 it is under development by Team Fusion Simulations. In 2017 that latter released an improved version of the game under the name IL-2 Sturmovik: Cliffs of Dover - Blitz which started the so called Dover series. The basic Blitz game represents the Battle of Britain during the Summer of 1940 while an add-on released in 2020 represents the air combats during the Western Desert campaign in North Africa in the period of 1940-1943. A second add-on, thus introducing in the game a third theatre of operations, is in the works, but no release date has been announced yet.
