SSN-589 DOWN is a role playing game written for the 24-hour RPG competition of May-June 2012. It's fast paced, game-master-less, cooperative and competitive at the same time, and best with three players or more. All you'll further need is these rules, a deck of playing cards, a different pawn for each player, and a coin.
It is late in May 1968, in the middle of the Cold War and the Vietnam conflict. Far out in the Atlantic, Nuclear Attack Sub Scorpion breaks all radio contact. Then, for reasons unknown, the vessel sinks to critical depth. Its hull cracks. 99 men and women are lost. What happened?
You are captain, crew and VIP guests on board, starting twenty-four hours earlier. Will you learn what went wrong? Can you change history, and save their lives?
