What if America seized absolute power after WWII?

In this alternate history scenario, the United States emerges from the war not only as the leader of the free world, but as a nation determined to bend the globe to its will. With unmatched military might and a monopoly on nuclear weapons, America embarks on a campaign of dominance where democracy and liberty serve only as banners masking ruthless expansion.

It’s up to you to lead the United States through a brutal campaign of conquest, leveraging overwhelming force and a devastating nuclear arsenal to bring the world under American control. The human cost will be staggering, but so too will be the reach of your empire.

Campaign Overview

The year is 1949. The world is still reeling from the devastation of WWII, but the dawn of the nuclear age has opened a new and terrifying chapter. Just four years after Hiroshima and Nagasaki, the Soviet Union detonates its first atomic bomb. The United States, emboldened and fearful in equal measure, decides that the only path to lasting peace is total dominance. From this moment forward, no rival power can be allowed to rise.

Take command of the United States in an alternate single player campaign, where you will crush resistance, impose order, and reshape the world in America’s image.
