Blitzkrieg 2: Fall of the Reich Summary
FoTR is a fairly run of the mill expansion pack that offers few new incentives in terms of missions or units, and it's not something for every WWII RTS gamer to snatch up.
The Blitzkrieg strategy series is gearing up for more real-time war as developer Nival announce Blitzkrieg 3, which is due out for PC and Mac in 2015. It shuns politics and ideology for just plain war.
The USSR, the Axis and the Allies each have their own classic single-player campaigns, where we take the role of commanders in an "interactive story" which can blend in multiplayer.
