DEFCON is a minimalist real-time strategy game released in 2006 by Introversion Software that simulates global thermonuclear warfare. Players command forces across a stylised world map, managing units, timing strikes, and assessing damage in escalating phases that force difficult decisions about escalation and restraint. The game is priced at $11.99 USD, supports both single-player and online co-operative play, and is marked as playable on Steam Deck. Reviewers and players have described the experience as bleak and tense, noting that its sparse presentation and restrained soundtrack amplify the dread of managing catastrophic conflict. The simple mechanics are said to breed considerable strategic depth, with multiplayer sessions creating chaotic and memorable encounters. It holds an 88% positive rating from over 2,700 Steam reviews.

About DEFCON: Inspired by the 1983 cult classic film, Wargames, DEFCON superbly evokes the tension, paranoia and suspicion of the Cold War era, playing on the fascinating aspects of psychological gameplay that occur during strategic nuclear warfare.
