In this expansion you will find seven new roles 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: one player plays against the others! You may also play with 5 players and play on Legendary level!
