Humans are a resilient bunch and won’t be exterminated easily. Stay on your toes as you work through the randomized Event deck. Drawn at the beginning of each round, one of these cards can be a boonÃ¢â‚¬â€or a burdenÃ¢â‚¬â€to your efforts. A massive bird migration could spread diseases to new cities or a handwashing awareness campaign could limit your options. Worse yet, as you and your opponents become more deadly, the World Health Organization will try to devise ways to stop you. AdaptÃ‚Â to the circumstances and you could become the disease that exterminates humanity!
