As the name implies, the game is focused on the fighting around Stalingrad and the end of Case Blau in late '42. There are several scenarios of various sizes and one monster campaign that covers Operation Uranus from start to finish. There are three different scales represented in the scenarios. The game is based on Atomics old V for Victory series and look similar. From a realism perspective, the games are fairly good.
Fog of war is implemented in several ways.
I like this feature a lot. However, if you take some of the negative options, or give the computer some favourable ones and you get a pretty good game. The campaign game is truly large. The game comes with a large map. They also have a ladder.
