Manage global nuclear diplomacy in this simulator inspired by WarGames and DEFCON.

The Doomsday Clock is constantly ticking down towards the destruction of the human race.

Engage in diplomacy, propaganda, subterfuge, and intimidation to turn back the clock by any means necessary. Convince the world's nuclear powers to agree to a global Armistice before they decide to hit the big red button. Do everything in your power to stop the countdown to extinction.

NOTE: The game STARTS PAUSED by default! You can use the buttons near the clock to control time, or use the keybinds Spacebar (pause/unpause), 1 (1x speed), and 2 (2x speed).

This game was made as a collaboration between four devs for the 2026 GMTK Game Jam. The theme for the jam was "countdown."
