History NightmareFuel / PlagueInc

* The Scenario Creator. Thought the horror was only what Ndemic could conjure up? Now the fans have their own brand of horror to unleash.
** Though the horror becomes a lot weaker when you consider the fact that a lot of custom scenarios are silly jokes, and even those who are serious tend to crack jokes every once in a while.

** In the UsefulNotes/{{Steam}} version of the game, occasionally you can clearly hear a child singing parts of ''"Ring Around the Rosie"'' near the end of the game (More specifically, "...ashes, ashes, we all fall down..."), and in the mobile version the sound is slightly longer (again, "Ring-a-round the rosie, A pocket full of posies, Ashes! Ashes! We all fall down...").

Remember ''VideoGame/{{Pandemic}}?'' That online game where you infect the world and watch it die? ''Plague Inc.'' is this concept, scarier, [[ShownTheirWork much more accurate]], and [[SurprisinglyRealisticOutcome much more realistic]]. By the end of your infection, this will invariably [[NightmareFuel creep out some players]].

* The City Cams in Evolved showing the collapse of society in many different countries. The view gets more cracked and red-tinted as a country dissolves into total anarchy... until it [[NothingIsScarier completely quiets down]] and the screen shows nothing but an abandoned, ruined city/town full of body bags (sometimes ''actual corpses'' instead) and wrecked cars.

* Even the Christmas scenario has its dark side: for starters, the fact that [[DayOfTheJackboot the world has become such a fascist hellhole that just BEING HAPPY is banned]]. It's played for laughs, but try to imagine what such a world would be like in RealLife: being forced to work all the time, or having your political career ruined because you were accused of laughing--not at an inappropriate time or place, just ''laughing'', period--both of which are alluded to in the news ticker.

*** "'Anti-fun squad'" [[PeoplesRepublicOfTyranny wins uncontested reelection."]]

** While enslaving humanity is one option available to the Neurax Worm, it's fully capable of simply killing everyone like the other plagues and even has a variety of unique lethal symptoms. These include [[DrivenToSuicide driving the infected to suicidal despair]], [[ParasiteZombie forcing them to attack and kill authority figures and unifected]], and outright [[BodyHorror digesting the hosts' brains]].

*** What's worse is that the Frozen Virus is actually called "Pithovirus", [[https://en.m.wikipedia.org/wiki/Pithovirus a VERY REAL virus.]] And [[ShownTheirWork almost everything about the Pithovirus in this game is entirely accurate to the real deal]]. Meaning this virus [[ParanoiaFuel could potentially cause a global pandemic]]. [[FearIsTheAppropriateResponse Be afraid. Be VERY afraid.]]

** [[KillEmAll Horrific slaughter]] in (country).

* The official scenario Fake News is funny in concept because you can create false rumours to deceive people. As you get further into the game, however, you eventually drive people off the rocker to the point you can make the deceived public do ''anything'' to destroy fact checkers before they expose your news as fake. You can make the deceived impersonate actual fact checkers, hire fake experts to the point of getting actual politicians involved, shuffle information to confuse the already informed public, and basically do any horrible thing to sabotage the opposition before your scandal is exposed as a farce. In the end, you succeed in driving humanity insane to the point that nothing is considered the truth anymore, and your reward for beating it is three biohazards. Part of the horror is also TruthInTelevision, with the sheer power of media, the Internet and how easy it is to forget that you shouldn't believe in everything you see or read.

** The [[https://www.youtube.com/watch?v=7GpsP49foWM music in Cure Mode]] isn't too scary, but the gameplay helps to invoke feelings of stress, uncertainty and dread. As you're the only one who is trying to save humanity from a deadly disease, you're also trying to the world to cooperate with you while saving the people from dying. The tone does not help into making you wonder if you'll be able to develop the cure before people had enough and fire you.

* The Neurax Worm is a PuppeteerParasite taken UpToEleven. At first it'll start off harmless, as described by scientists; but by the time you've upgraded, humanity won't be able to react quickly enough to stop the infection from spreading, and the cure can be stopped in a single upgrade of a symptom. The image of the plague also changes from a Petri dish to a worm sitting on a brain with tendrils extending inside it, eventually [[NauseaFuel expanding to all of the brain, turning it a sickly orange, and causing flesh bubbles to pop out]]. The worm seems almost intelligent in its symptoms, such as causing people to fly to a specific country in order to infect it, even if that country has closed off its airports (or has no airports). Another symptom involves violent attacks against anyone who isn't infected, and active attempts to stop cure research. The starting blurb mentions that the worm has been dormant for millennia only to be uncovered by excavation. Additional news mention people worshiping the worm, achieved with the Transcendence symptom. Notice how it gives a ''massive'' boost to Severity.
