There is no consensus on the global let-go of nuclear proliferation. The game explores various hurdles to the consensus.

Played as two teams (the United States and Russia), the goal of the game is to achieve non-profileration by getting the NPT signed by all non-player characters of the game including a signature from the opposing team.

The non-player characters are opposed to the treaty. Using cards provided, the team members try to persuade the characters into signing the treaty. The game involves a lot of polemic and clever thinking from both players and non-players.
