Plague Inc. is an iOS and Android strategy video game, developed by one-man developer Ndemic Creations. 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.
The PC and upcoming Xbox One version is entitled Plague Inc: Evolved, which includes adjustments and additions to gameplay.
It has been downloaded over 25 million times and was a runner up in the IGN Game of the Year 2012 awards for ‘Overall Best Strategy Game’. Overall, it was the 15th most downloaded paid iPhone game of 2012 in the U.S. and the 5th most downloaded paid iPhone game of 2013 in the U.S. In February 2014, Ndemic Creations released Plague Inc: Evolved, for PC, Mac and Linux onto Steam. The game continues to have an active community and is regularly updated.
Plague Inc. is a strategy-simulation game in which the player controls a plague which has infected patient zero. The player can choose between various plagues and viruses, and 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 exception to this rule is the game’s version of a zombie plague in which if you evolve the symptom “cytopathic reanimation,” it will eliminate the chance that the cure will affect anything except for high score.
The developer has said it is “a bit like the film Contagion except you are on the other side”. The game was inspired by Pandemic 2, a browser-based Flash game released in 2008 by Dark Realm Studios.
