The team mission is to prevent a worldwide pandemic outbreak, treating hot spots while researching cures for each of the four plagues before they get out of hand. Players must plan their strategy to mesh their specialists' strengths before the diseases overwhelm the world. 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 developing cures.
