There are actually two expansions out for WitE.
Don to the Danube:
This expansion to the award-winning War in the East comes with a wide array of later war scenarios ranging from short but intense 6 turn bouts like the Battle for Kharkov (1942) to immense 37-turn engagements taking place across multiple nations like Drama on the Danube (Summer 1944 – Spring 1945). Don to the Danube and the War in the East system gives players unprecedented control over pivotal operations in the Second World War like Operation Uranus, the encirclement of the 6th German Army at Stalingrad, the Cherkassy Pocket and much more.
Lost Battles:
Shorter scenarios like Operation Mars, Courland Pocket, Smolensk 1941, Operation Bagration, the Liberation of Leningrad and Operation Konrad bring you to some of the most interesting operations in World War II while keeping the time investment to 15 turns or less. Added to these are medium size scenarios like the Battle for Moscow, Vistula to Berlin and Winter 1942-43, as well as the immense new Stalingrad to Berlin campaign and a new sudden death victory variant of the main 1941-1945 campaign.
