Compatibility Between Editions
There are three different editions of IL-2 Sturmovik available - Battle of Stalingrad, Battle of Moscow and Battle of Kuban. They use a common client and authorization system, which allows a customer to use them separately or as a combined product. This approach allows players of both editions to encounter each other in multiplayer mode and streamlines updates and the addition of future content. All editions of the game include the standard gameplay modes and several maps that are available to all owners of the sim.
