Plague Inc: Evolved is a unique mix of high strategy and terrifyingly realistic simulation. Your pathogen has just infected 'Patient Zero' - now you must bring about the end of human history by evolving a deadly, global Plague whilst adapting against everything humanity can do to defend itself.

Plague Inc. is so realistic that the CDC even asked the developer to come and speak about the infection models in the game! http://blogs.cdc.gov/publichealthmatters/2013/04/plague-inc/.

Over 65 million players have been infected by Plague Inc. already. Now, Plague Inc: Evolved combines the original critically acclaimed gameplay with significant, all-new features for PC including multiplayer, user-generated content support, improved graphics and lots more.
