With awesome technology, the aggressors swept across the planet, sowing destruction as Tokyo, Berlin, and Washington, D.C., were A-bombed into submission. Russia, Nazi Germany, Japan, and the United States were not easily cowed, however. With cunning and incredible daring, they pressed every advantage against the invader's superior strength, and, led by Stalin, began to detonate their own atom bombs in retaliation.

City after city explodes in radioactive firestorms, and fears grow as the worldwide resources disappear; will there be any world left for the invaders to conquer, or for the uneasy allies to defend?

While Mao Tse-tung wages a desperate guerrilla war and Hitler drives his country toward self-destruction, U.S. forces frantically try to stop the enemy's push from coast to coast.

In this battle to stave off world domination, unless the once-great military powers take the risk of annihilating the human race, they'll risk losing the war.
