The game play centers on a map of the world where you can watch your disease spread from one country to another gradually infesting the whole world. Plague Inc. accumulates upgrades used for application e.g. complex symptoms, how the plague spreads, and its resistance towards the researched cure.
The game is quite addictive as the player has to constantly try and continue the plague’s evolvement before world countries can plan out research for its cure. The symptoms vary in levels leading to a faster viral spread and the majority of your time is spent on watching the plague reach different countries of the world.
Although the game may not contain that many big events or animations, you’ll still be able to experiment and continue to replay the game choosing new options every time for improving the spread rate of your plague. Plague Inc.’s polished game play fills the void left by its simple graphics.
