SGS Operation Downfall

We are all aware that the atomic bombings of August 1945 on Hiroshima and Nagasaki precipitated the Japanese surrender at the end of World Ward II. But what would have happened if the Manhattan Project has failed or known such delays that the bombs could not be made ready in time? In this game you will be able to experience the two landing and the overall amphibious assaults against the Japanese home islands in 1945 and 1946.
