DEFCON is a real-time strategy game created by Introversion Software, the developers of Darwinia, Multiwinia and Uplink. DEFCON was first released via download on September 2006 through Steam and Introversion’s webstore. In the United Kingdom it was released on high street stores on June 15, 2007 for a limited period included Uplink. On April 5, 2007, U.S. publisher Encore announced that it will publish the game in the United States, and had ordered an initial 50,000 copies of the game for retail. DEFCON gameplay is reminiscent of the “big boards” that visually represented thermonuclear war in films such as Dr. Strangelove, Fail-Safe, and especially WarGames.
