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 hot-spots while researching cures for each of four plagues before they get out of hand.
The game board depicts several major population centers on Earth. On each turn, a player can use up to four actions to travel between cities, treat infected populaces, discover a cure, or build a research station. A deck of cards provides the players with these abilities, but sprinkled throughout this deck are Epidemic! cards that accelerate and intensify the diseases' activity. A second, separate deck of cards controls the "normal" spread of the infections.
