Plague Inc: Evolved

Plague Inc: Evolved is a real-time strategy simulation video game, developed and published by UK-based independent games studio Ndemic Creations. The game is a remake of the developer's previous game, Plague Inc., for PC and consoles. In the game, the player creates and evolves a pathogen in an effort to destroy the world with a deadly plague. The game uses an epidemic model with a complex and realistic set of variables to simulate the spread and severity of the plague and has attracted the attention of the CDC.

Gameplay
The core game of Plague Inc: Evolved is the same as Plague Inc. - the player controls a plague which has infected patient zero. The player must infect and kill the whole world population by evolving the plague and adapting to various environments. However, there is a time pressure to complete the game before humans, the opponent, develop a cure for the plague. The developer has said that the game was inspired by Pandemic 2, a browser-based Flash game released in 2008 by Dark Realm Studios.

The game series has been praised by the Centers for Disease Control and Prevention who said "it uses a non-traditional route to raise public awareness on epidemiology, disease transmission, and diseases/pandemic information. The game creates a compelling world that engages the public on serious public health topics". The developer of the game was invited to give a talk at the CDC.
