DEFCON 1 is a fully asymmetrical strategy game for 2 to 5 players, which scales perfectly to different player counts thanks to its scenarios, and which does not neglect any variable of a fascinating historical period. The players control five different blocs - three major blocs (the Atlantic Alliance, the Warsaw Pact, the Non-Aligned Movement) and two minor blocs (France and China).
In DEFCON 1, each bloc has its strengths and weaknesses, using its own technological tree, its mission and objective cards, and even scalable pool of units. The Defcon level degrades during the game from 5 to 1, and the level degrades depending on the actions of the players, opening new strategical options that will become available, such as building nuclear bombs.
