Game InfoEdit

Special project. Allows your cities to build Atomic Bombs and Nuclear Missiles.


The Manhattan Project allows a civilization to construct nuclear weapons. Each civilization must complete it before it can construct nukes. Be wary of any civilization that has done so! A global alert will warn you of this important fact, which will even be supported by a sinister declaration if said civilization is hostile to you!

Note that in team games, only one member civilization of a given team can complete this project. All members will gain the ability to produce nuclear weapons.

Historical InfoEdit

The Manhattan Project is the code name for the Anglo-American effort to develop a nuclear bomb during World War II. The project was led by the US but included scientists and engineers from the United Kingdom and Canada. The US began serious efforts to create a nuclear bomb in the 1930s, but the program ramped up into high gear after the Japanese bombed Pearl Harbor in late 1941. Eventually the program would employ some 125,000 people and cost approximately $20 billion (in today's dollars). By 1945 the Manhattan Project had successfully constructed and tested nuclear weapons, and in early August of that year a uranium and a plutonium bomb were dropped upon Japan. Japan surrendered less than a week later, ending World War II.
