Pandemic

Pandemic has the player take control of a virus, which strives to become a deadly virus, spreading across the globe and wiping out all of mankind in 200 days. The player can upgrade their virus by choosing which symptoms it will exhibit and how it will spread (such as being waterborne or airborne or both). The goal is to become a dangerous virus, but also to become undetected enough to spread globally.

If the player's virus becomes too noticeable, the countries will close their borders, keeping their virus from spreading any further. To upgrade their virus, they will receive points on how much the disease spreads and kills, after a certain number of days, points will be awarded and the player can go to the upgrade screen to make their disease more powerful.
