The single-player mode features 3 campaigns (German, Allied or Soviet) with over 20 missions and modding support is planned. Each of the missions in the different campaigns are based on real life World War II battles/invasions. For example, in the German campaign the player commands the Wehrmacht in the Battle of France, Operation Barbarossa, the Battle of Stalingrad, the Battle of Kursk and the Battle of the Bulge. The Invasion of Poland is used as a tutorial for the game and also acts as a prelude to the German campaign. Post-release DLCs features additional campaigns set in other theatres such as North African campaign, Winter War, Battle of Dunkirk and Pacific War.
