In Pandemic, several virulent diseases have broken out simultaneously all over the world! The players are disease-fighting specialists whose mission is to treat disease hotspots while researching cures for each of four plagues before they get out of hand. Taking a unique role within the team, players must plan their strategy to mesh with their specialists' strengths in order to conquer the diseases. For example, the Operations Expert can build research stations which are needed to find cures for the diseases and which allow for greater mobility between cities; the Scientist needs only four cards of a particular disease to cure it instead of the normal five—but the diseases are spreading quickly and time is running out. If one or more diseases spreads beyond recovery or if too much time elapses, the players all lose. If they cure the four diseases, they all win!
