The Co-Op Experience

Co-operative multiplayer mode allows several players to work together to win the war with up to 32 players. You can either form alliances with other countries and cooperate that way or actually share control of the same country. In this case however make sure that you are on the same page which actions are done by whom.

Guide your nation to glory between 1936 and 1948 and wage war, conduct diplomacy and build your industry in the most detailed World War 2 game ever made.
