Plague Inc: Evolved

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.

Plague Inc: Evolved went live on Steam Early Access on 20 February 2014.

In 2014, the developer used "almost half a million pieces of feedback and feature requests from players" to help him understand what players wanted from the game and said he was "only 50 percent of the way through the original Plague Inc. design document".

The Xbox One version of Plague Inc. Evolved has received "generally favorable reviews" from review aggregator Metacritic. Critics gave the game an average score of 80 out of 100.

In March 2016, the Italian edition of Eurogamer gave the game a 7 out of 10 score, praising the game for its relatively complex gameplay but mildly criticising it for a lack of depth caused by its origins as a mobile game.
