Ostfront: Decisive Battles in the East
is an unofficial expansion for the IL-2 Sturmovik: Forgotten Battles
flight simulator and required the original game to play. Players fly in 24 campaigns over Murmansk and Kurland for the Red Airforce, Luftwaffe, RAF or the French Regiment Normandie-Niemen. There is also a bonus campaign Schlachtflieger to fly a Hs-123/Cr-42 in low level strafing and bombing missions in 1944.
