S&T: WWII is a classic turn-based strategy game that offers three campaigns and 18 historical missions from WWII. You will need to juggle your military, your economy and scientific developments in order to  be victorious in your battles. There is a multiplayer element that will let you kick back and dominate your friends and some skirmish mode maps to keep you challenged and playing. You can command the Axis to conquer Europe and then take control of the armies of the UUSR and Allies to crush them and take it back.
