List of Scenarios

Scenario Name Scenario Icon Scenario Description Added in mutation
Fake News Scenario fake news.png From wild conspiracy theories to election campaign mudslinging, we now live in a post-fact world where falsehoods and misinformation can spread around just like a disease. In this radically different scenario you'll create your very own Fake News story and shape it using all the modern tools and psychological tricks at your disposal. Can you deceive the world?

Ultimate Board Games Scenario ubg.png Make a best-selling board game in this radically different scenario that has nothing to do with disease! Investors have given you two years to design, produce and distribute your very own game - but can you make it a best selling hit? *Insert witty subliminal marketing about Plague Inc: The Board Game here* :P 1.16
Science Denial Scenario science denial.png People no longer believe in science. Popular opinion has shifted against objective truth and towards 'alternative facts'. But when a terrifying new plague is unleashed, ginkgo tree extract, healing crystals and snake oil can only do so much. Can the exiled experts save the world? 1.16
Mad Cow Disease Scenario mad cow disease.png Panic over BSE almost shut down the beef industry in the 1990s. Imports were banned and burgers were off the menu until humanity got things under control. Recently though, unforeseen protein folding has resulted in a new variant of the prion - putting the whole food chain at risk. Is now the time to go vegetarian?

Flight Club Scenario flight club.png Huge leaps in aviation technology have seen humanity unlock the true potential of suborbital flight on a commercial basis. In this future world you can get from London to Sydney in 2 hours for a fraction of the cost, and every country has an airport. Does the idea of Greenland getting a major airport excite you? 1.15
Where Is Everyone? Scenario where is everyone.png Almost everybody in the world has mysteriously vanished and nobody knows why. The Rapture? Mass abductions? Spontaneous combustion? Who knows?! Luckily though, the few thousand people left behind are carrying on as normal. How will your outbreak spread when there are so few people left to infect? 1.15
Santa's Little Helper Little helper.png The world is dark and gloomy. Boring governments worldwide have banned holidays, laughter and celebrations. Humanity has forgotten how to have fun - people dress in grey and spend all their time working. Luckily, the Neurax Worm has teamed up with Santa and is determined to infect the world with joy and happiness.
Can Santa's little helper make a miracle happen?
Teleportation Teleportation.png Highly advanced technology has created the opportunity to travel through a portal and teleport to other countries. Meanwhile, after playing realistic plague simulator video games, humans have worked out which countries are likely to be the safest in the event of a global pandemic.
Will they put this knowledge to good use?
Artificial Organs mrath glp Rapid advances in medical science allow for the production of advanced artificial organs. As production ramps up, it is hoped that the ability to replace organs will significantly improve life expectancy.
Is humanity on the brink of immortality?
Frozen Virus Frozen Virus Scenario Logo.png A giant virus, frozen deep in the Siberian permafrost, has thawed and infected an unknown victim.
Dormant for over 30,000 years, it was last active at a time when mammoths and Neanderthals roamed the world. Its ancient genetic structure pre-dates homo sapiens but its DNA has been severely degraded.
Does it have what it takes to send humanity back to the stone age?

Nipah Virus Scenario nipah virus.png Rapid urbanisation in India accelerates human encroachment into animal habitats whilst a new strain of the Nipah Virus spreads fast through fruit bat colonies. Genetic crossover with other species of the Henipavirus genus could enable enhanced cross-species transmission - resulting in a Contagion worthy of Hollywood.
Could this be the most deadly Nipah outbreak ever?

Unknown Origin Scenario unknown origin.png Everyone has a favorite country, unfortunately you don't get to choose it here...
Are you feeling lucky?
Black Death Scenario black death.png Patient Zero is infected with a previously dormant strain of Yersinia pestis from an unknown origin. Humanity must face a deadly bacterium that has been hidden for centuries - previously killing over 200 million people. However, the world has changed a lot in 700 years with better hygiene and more antibiotics.
Will the disease be able to adapt and spread before its victims die off?

Created Equal Scenario global health.png People worldwide agree that a disease free world is a moral imperative. New global programme to improve surveillance capacity significantly increases ability of poor countries to identify, respond to and communicate about national disease outbreaks.
If the world stands together, nothing can stop it?
Global Warming Scenario global warming.png Huge releases of greenhouse gases significantly accelerate global warming and raise the global surface temperature by over 6°C as well as triggering other climate change events and flooding of low lying countries.
Out of the frying pan?
Golden Age Scenario develop this.png A global growth surge brings huge economic gains that primarily benefit the people at the bottom of the pyramid, improving the quality of life for billions. Healthcare and research is significantly improved worldwide.
Can humanity be stopped?
Ice Age Scenario global cooling.png Solar variation reduces the amount of radiation emitted by the sun, triggering a minor ice age and lowering the global surface temperature by more than 5°C as well as triggering other climate change events.
Is hell freezing over?
Mirror Earth Scenario opposites world.png Step through the mirror into the land of opposites where hot becomes cold and cold becomes hot, rich becomes poor and... You get the idea!
Which disease will be the fairest of them all?
Pirate Plague Scenario ocean piracy.png Maritime piracy increases worldwide and poses a major threat to international shipping. Global sea transport and trade is significantly reduced, changing the way that people travel.
How will anyone get to Greenland now?
Shut Down Everything Scenario shut down.png Recent health scares from SARS, H5N1 and H1N1 raised awareness of how quickly disease can spread. Governments are extremely concerned about the international spread of disease and people around the world are demanding that countries take pre-emptive action.
Can the world be infected before countries shut down everything?
Smallpox Scenario smallpox.png Patient Zero is infected with a strain of Variola major that escaped from a lab. Humanity eradicated Smallpox over 30 years ago and has a detailed knowledge of the virus as well as powerful vaccination programmes.
Will this be enough to stop the deadliest diseases that mankind ever known...?

Sovereign Default Scenario financial meltdown.png A failure to extend the debt ceiling in the US triggers a major financial rebalancing. A few countries benefit but most suffer catastrophic damage to their economics with knock on impacts on healthcare and research capability.
Can things get any worse?
Swine Flu Scenario swine flu.png Patient Zero is infected with a new mutated strain of the Influenza A (H1N1) virus. A reassortment of the 2009 strain with limited lethality - existing anti-virals are moderately effective against it. However, analysis of its genetic make-up has identified potential sequence similarities to the 1918 'Spanish Flu' strain that killed 5% of the world's population.
Will history repeat itself?

Volcanic Ash Scenario volcanic ash.png Massive volumes of volcanic ash are ejected into the atmosphere from major volcanic eruptions. The majority of flights worldwide are grounded, changing the way that people travel.
Does this cloud have a silver lining?
Who Cares Scenario who cares.png Increased popularity of reality TV in rich countries distracts people and stops them caring about disease outbreaks in poorer countries. Reduced funding significantly impacts the surveillance capacity of poor countries and limits their ability to identify and respond to national disease outbreaks.
Who cares what happens to poor people?
Xenophobia Scenario xenophobia.png Anger over immigration, globalisation and exploitations trigger a rapid increase in hostility towards foreigners worldwide. Countries heavily fortify their borders - significantly reducing the amount of cross border traffic worldwide.
On a positive note, border guards get to shout "You shall not pass"...


In-App Purchases (mobile version only)

Next scenario: $0.99 USD (unlocks the next scenario)

All scenarios: $2.99 USD (unlocks all current and future scenarios)

Plague Pack: $10.99 USD or $4.99 USD if all normal and special plagues are unlocked (unlocks all scenarios and plagues; normal and special)

The reasons why scenarios cost money in the mobile version:

"Scenarios are a new, optional expansion pack to the original Plague Inc. game. (which released back in May 2012!) A one off purchase unlocks all current and future scenarios.

The Scenarios expansion pack costs money because it adds loads of new content to the original game and it took me months of hard work to make. It will give you hours of extra gameplay and I believe it offers fair value for money.

I hope you understand why I made this decision and that you feel fairly treated.
