Plague Inc: Evolved is a strategy game developed by Ndemic Creations that lets players control a deadly disease, with the goal of infecting and killing all the people in the world. The game is available on the PlayStation 4 platform and falls under the Games category with a subcategory of Strategy.

The game begins with the player infecting patient zero in a selected country, and from there on, the disease spreads across borders, carried by animals, birds, insects, blood, or public transport. The game offers both random and controlled infections, with laboratory accidents being categorized as random infections while spore activations, zombie dislocation, and trojan planes are controlled by the player.

As the player progresses, they earn DNA points by infecting and killing humans, which can be spent on upgrading the disease. The game also features a mutation system, where a combination of symptoms can mutate into a more contagious and lethal disease.

Plague Inc: Evolved offers three aspects to player-created diseases: infectiousness, severity, and lethality. The player has a limited time to infect the population, as humans may be able to produce a cure.
