The game focuses on real events of the World War II. There are four campaigns; two of them are on the Pacific islands, and two of them in Europe. The player is able to play for the American or Japanese armies in the Pacific, and for the Allies or Germans in Europe. This is the first RTS engine to render accurate vast marine and land battlefields (maps contain more than 150 "virtual" square kilometers). The game introduces tight team play between all arms of the fighting forces: Naval battles supported by aviations - There are short- and long-range bomber, torpedo bombers, attack bombers, fighters, and transports. Groups of ships with carriers are a powerful force capable of not only to conduct operations at sea, but also to support the large ground operations (supported by carrier-based aircrafts and large-caliber on-ship guns). Submarines and aviation hunting enemy's transport ships caravans - Using different types of submarines in special operations, one can make sudden strikes on transports and battle ships of opponents; if the strike succeeds, the enemy will lose part of the reinforcement, and will lose opportunity to have significant navy. Radar systems allow players to more successfully defend of air and naval attacks of opponents.
