This World War II naval simulation game puts you in command of American and Japanese forces in December 1941. The American forces have been placed on alert due to a breakdown in negotiations with Japan. Attacking Japanese task forces are indeed steaming across the Pacific, planning to launch attacks on locations unknown.
The game starts on a strategic map covering an area of the Pacific Ocean encompassing Hawaii, Midway and Wake. The game switches to tactical battle displays for surface combat and air strikes. Play options include: selecting a date for the attack (from December 1st to 12th), selecting custom task force groupings for your ships, and adjusting the starting locations of your task forces.
The game encompasses carrier air operations, land base bombardment and capture, submarines, and weather (wind, rough seas, and fog). Each game turn constitutes two hours.
