In this expansion you will find six new roles (plus 1 revised OpEx and a Bio-Terroritst), eight new special events, and several challenge kits to be added to the basic game play.

Virulent Strain challenge: makes one disease become particularly deadly in unpredictable ways.

Mutation Challenge: adds a fifth (purple) disease that behaves differently than the original four.

Bio-Terrorist Challenge: pits one player against the others!

You may also play with 5 players and play on Legendary level!

Other components include: 12 purple disease cubes, 12 pawns in a smaller size, petri dishes to store your diseases and pawns, a bio-terrorist pad for that player to record his actions.

NOTE TO FIRST EDITION PANDEMIC OWNERS: If your cards are gloss with no linen finish then you have a first printing (Feb-April 2008). Z-Man Games is offering a trade in so that your cards will match the newer printings which have a linen finish. For more information please visit Z-Man Games.
