Ill post some key features:
Set in the beginning of 1941, the players role will take him from the defense of stalingrad to the victory at berlin.
Graphics look amazing the soldiers look just as good as they do in other ww2 firstperson shooters.
Realistic snow, tank treads make realistic marks, also tanks can get bogged down in snow drifts.
Snow melts Eg: a soldier with a flamethrower burns a farmhouse the snow on the roof melts and makes the roof fallin.
You can vault over fences.
New Feature called "True Sight" You can only see what your units see.
More advanced covering system...thats all it says about that.
