Gameplay
''Plague Inc.'' is a strategy-simulation game in which the player indirectly controls a plague, which has infected patient zero. The player can choose between game modes and pathogens and complete the objective set by the game mode by evolving the plague and adapting to various environments. The goals include but are not limited to, infecting and killing the world's population with a pathogen, enslaving the world's population with the 'Neurax Worm', converting the world's population into zombies with the 'Necroa Virus'(which eventually became the basis for After Inc.).establishing the Planet of the Apes with the 'Simian Flu', or corrupting humanity with the 'Shadow Plague'. However, there is a time pressure to complete the game before humans (the opponent) develop a cure for the plague.
The developer has said it is 'a bit like the film ''
Contagion'' except you are on the other side'. The film ''Contagion'' was a partial inspiration for the game, according to the developer. The developer has said the game was partially inspired by ''Pandemic 2'', a browser-based
Flash game released in 2008 by Dark Realm Studios.
