Pandemic is a cooperative board game and was first published by Z-Man Games in the United States in 2008.Pandemic is based on the premise that four diseases have broken out in the world, each threatening to wipe out a region. The game accommodates two to four players, each playing one of seven possible roles: dispatcher, medic, scientist, researcher, operations expert, contingency planner, or quarantine specialist. Through the combined effort of all the players, the goal is to discover all four cures before any of several game-losing conditions are reached.
