The world is on the brink of Armageddon. A full-scale global thermonuclear war has broken out, and as a general in a bunker somewhere, you must direct your offensive and defensive systems to nuke your opponents. Nobody wins, but maybe you can lose the least. Everybody dies.
An online multiplayer strategy, but it can be played in a singleplayer mode. You place units, like missile silos, airbases and radar dishes, on their territorial maps, and the game counts down from DEFCON 5 to DEFCON 1, during which time the players are to make strategic choices to eliminate their opponents without losing too much themselves.
Gameplay is shown on a world map and action is represented by icons and lines similar of the drawing style of their 2 previous games: Darwinia and Uplink.
