From the ashes of war, nations rise to power in the atomic age. Each player takes control of a nation struggling for power in the latter part of the 20th century. They build up their nation’s industry, commerce, and government by acquiring resources, building structures, and tapping sources of energy. The price of oil is going up, and nuclear energy is the wave of the future. The Manhattan Project: Energy Empire is set in the same "universe" as The Manhattan Project, but it's a standalone game, not an expansion.
