Downfall is a simplistic puzzle game, where you can place quarantine on tiles to contain the infection. Beware of the severs which can quickly spread the virus over longer distances, industry zones which spreads the virus farther, and rivers that quickly spreads the virus along the way.
Earn as much stars as you can, saving three cities is always possible. But sometimes you have to sacrifice some cities to save more cities.
