About DEFCON
DEFCON is a Cold War-era strategy game that simulates global thermonuclear war. From an underground bunker, you position submarines, silos and air defenses, then make nuclear attacks while trying to protect your own population and annihilate the enemy’s. Every attack exposes you to retaliation, so each decision risks revealing your vulnerabilities.
Alliances and brinkmanship
In multiplayer, you form alliances that can quickly give way to betrayal. You balance aggression against self-preservation as you try to avoid triggering total nuclear war. The goal is to lose fewer people than your opponents: in a nuclear Armageddon, everybody loses.
The cost of war
A minimalist, military-style interface and soundscape create a tense view of the conflict. Real-time death tolls track the human impact as cities are destroyed and the globe plunges into darkness.
