P.T.O.: Pacific Theater of Operations II, known in Japan as Teitoku no Ketsudan II ("The Admiral's Decision II"), is a turn-based strategy game from Koei and part of their World War series. It follows the original P.T.O. from 1990 and was released for NEC PC-9801 - its original platform - as well as the Sega Saturn, Super Nintendo, Sony PlayStation, PC DOS and the FM Towns.
The player directs the Japanese Imperial naval forces in the Pacific Ocean in their war against the United States as part of the wider conflict between the Axis and Allies during World War II. The events roughly follow the chronological events of WWII, culminating in a desperate attack with the legendary Japanese warship Yamato shortly before Japan's surrender in 1945.
