IL-2 Sturmovik is a series of games concentrating on the accurate simulation of World War II aerial warfare. It was unusual in that it was written by a Russian company 1C: Maddox (now 1C: Publishing) and the games originally focused on the war on the Eastern front.
The first in the series "IL-2 Sturmovik" was released on PC in 2001. A sequel was released in 2002. This game "IL-2 Sturmovik: Forgotten Battles" received two expansion packs, one of which substantially expanded the game to include the war in the Pacific, introducing carrier-based aircraft.
A final standalone expansion "IL-2 Sturmovik: 1946" released in 2006 included Forgotten Battles and both it's expansions along with aircraft which were still in development at the end of World War II which could be flown in a series of "Alternate History" campaigns.
The PC games were characterised by large numbers of flyable aircraft, with more released in expansions and patches throughout the life of the product, and a high degree of accuracy in the flight model and aircraft models.
In 2009, the series moved to consoles with the release of "IL-2 Sturmovik: Birds Of Prey" for the XBox 360 and Playstation 3.
