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.
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.
