This expansion adds two thrilling challenges to the dice-based Pandemic: The Cure.You've traveled the world, collected disease samples, and researched cures. But new challenges are emerging. The Experimental Meds super-expansion builds on the Pandemic: The Cure dice-based game of curing diseases. Adapt to the escalating situation as a fifth purple disease with a unique set of dice behaves in unpredictable ways. Purple dice can lead to even more infections or modify your attempts to find a cure in strange—and sometimes beneficial—ways. Counter this threat with one of the eight new roles, including the Celebrity Activist, Archivist, and Field Director. Each role brings its own game altering abilities and dice to the table, offering even more varied approaches to your disease-fighting efforts. Combined with the eleven new event cards, Experimental Meds provides tools to handle any threat. If you're looking for even more of a challenge, try the Hot Zones Challenge. Rather than representing a new disease, the eleven Hot Zone dice represent different effects—positive and negative—that existing diseases have on that region. Some results might let you move a hot zone or infection die from your current region to an adjacent one. Others might force you to spend extra dice to travel to a region, or draw an additional infection die from the bag during an outbreak. No matter what dice are present, each hot zone offers a unique challenge to you and your team. This product is an expansion: Pandemic: The Cure base game required to play.
