Four diseases have broken out in the world and it is up to a team of specialists in various fields to find cures for these diseases before mankind is wiped out in this cooperative game. Players must work together, playing to their characters' strengths and planning their strategy of eradication before the diseases overwhelm the world with ever-increasing outbreaks. For example, the Operation Specialist can build research stations, which are needed to find cures for the diseases. The Scientist needs only four cards of a particular disease to cure it instead of the normal five. But the diseases are breaking out fast, and time is running out: the team must try to stem the tide of infection in diseased areas while also towards cures.
