In order of difficulty, the campaigns feature Germany (1943), the United States (1944), Russia (1944-1945), Britain (1944), and Japan (1942-1945), though they can be played in any order. In the five campaigns, based on specific World War II events, you play as one of five different nations at various points in the conflict. Fireglow follows up its near million seller Sudden Strike with a sequel featuring more than 40 new missions, playable separately or in five campaigns, 50-plus new units (bringing the total to more than 150), and up to a thousand active units per scenario.
