From the Game Manual:
BIG THREE is the ultimate WWII strategy game. You control all the action from the desolate fiords of Norway to the scorching sands of Egypt, from the strategic Rock of Gibralter to the frozen streets of Moscow. Recreate the epic and fiercely fought battles of Tobruk and Stalingrad. Decide to open your second front in Normandy or the "soft underbelly" of Europe (Italy). Build bombers to hit your opponent's cities or build tanks and fighters to encircle and destroy his armies at the front. BIG THREE gives you all this in an easy-to-use format plus excellent graphics.
Each player assumes supreme command of the Axis, Allied or Soviet forces in Europe during 1939-1945. Players can choose from three scenarios or a previously saved game. Players that perform better than their historical counterparts will normally win and those that under perform will normally lose.
