Pandemic is based on the premise that diseases have broken out in the world, each threatening to wipe out a region. The game accommodates 2 to 5 players, each playing one of six possible specialists: (dispatcher, medic, scientist, researcher, containment, or operations expert). The game is cooperative, rather than competitive. Through the combined effort of all the players, the goal is to discover all cures before any of several game-losing conditions are reached.
