The free demo includes 2 campaigns as a small sample of what the full game offers:

1939 World At War campaign limited to 10 months of playing time - This is the main global campaign covering the entire war from start to finish. Players will be able to wage war across Europe, the Atlantic, North Africa, Asia and the Pacific.
1948 World At War campaign limited to 4 months of playing time - With the Axis powers soundly defeated, the Western Allies' alliance with the USSR and China becomes fractured as ideology now trumps previous allegiances... This is World War III!

Multiplayer modes, saving and unit purchases are disabled in the demo but the campaign is playable against the AI as either side.

It's here! Strategic Command World War Two Global Conflict GOLD is the brand new expansion to the original SC WWII Global Conflict game of grand strategy and global world dominance in the 1940's.

SC WWII Global Conflict GOLD boasts dozens of major new features, changes and improvements to the original game (such as a new interface and fast AI), as well as 4(!) new major campaigns, 4 entirely reworked campaigns (to include the new features), and a whole lot more!
