What it is
DEFCON is a real-time strategy game by Introversion Software, released in 2006 for Windows, macOS and Linux. It simulates global nuclear conflict through the positioning of submarines, missile silos and air defenses, with players trying to damage opponents while protecting their own populations. Every attack can expose weaknesses and invite retaliation, while alliances and betrayals shape multiplayer play. Its minimalist military-style interface displays death tolls in real time, keeping the consequences of attacks visible as the conflict escalates. The game supports single-player and multiplayer, including PvP and co-op over online or LAN connections, as well as cross-platform multiplayer. Its Cold War setting and emphasis on brinkmanship make decision-making as much about restraint and self-preservation as aggression. DEFCON is listed in the indie and strategy genres, with Steam Achievements included.
