Inspired by the 1983 film WarGames, Introversion Software's DefCon is a game of global thermonuclear war. Since no one ever wins in a game of nuclear war, the object of DefCon is to lose the least. In control of global nation-states such as America, Russia, or Europe, players vie to best position their countries to survive the pending Armageddon, by strategically deploying their armed forces, firing their missiles, and making and breaking alliances with other nations. The game can be played solo, or against other human competitors online. The initial release of DefCon is available for download through Valve Software's "Steam" service, or in a boxed version ordered directly from Introversion's website. ~ T.J. Deci, All Game Guide
