Fortress America is a strategic board game designed by Michael Gray and published in 1986 by Milton Bradley. Fortress America was the fourth of five games in the Gamemaster series.
Set in the 21st century, the board game begins with the premise that during the Cold War, nuclear terrorists destroyed much of the Middle East's supply of oil. In response, the United States launched into orbit a satellite based solar-power system to solve the energy crisis. At the same time, the U.S. had perfected the so-called "Star Wars" technology and incorporated a satellite-based laser system into the solar satellites. This system was capable of destroying intercontinental ballistic missiles (ICBMs) before impact. Thus, the USA was completely safe from nuclear threat, ending the era of Mutual Assured Destruction.
This creates a great deal of political turmoil - the USSR is especially upset at the nuclear balance of power being shifted - and while the rest of the world realigns in various ways (through alliances and treaties as well as conventional military conflict) the United States, complacent in its technical superiority, becomes isolationist in nature.
The game opens with the world divided into three major world powers outside of the US:
1) The Asian Peoples Alliance (yellow player)
2) The Central American Federation (blue player)
