You have found the cure for four deadly diseases. But what happens when the diseases become stronger? Even worse, what happens when someone spreads them on purpose?!
Return to the world of pandemics with On the Brink, and prepare for the unexpected. The three challenges included in this expansion develop the base game mechanics in exciting ways. A disease can become a virulent strain and become harder to treat as the game progresses. Or you can introduce a fifth disease with the mutation challenge, and watch it appear in unexpected places.
Teamwork is even more important if a fifth player dons the Bio-Terrorist's mask and spreads panic while moving secretly across the board. You can try all the challenges individually, or combine them for an even greater challenge!
