Free DLC conditions
Our first DLC Plague Inc: The Cure was given away for free during the COVID Pandemic, as we didn't want to profit from a serious incident that was affecting everybody!
Equally, we pledge that if an alien invasion* happens - Ndemic will adopt the same approach and give A&A away for free for the duration of the invasion.
*Invasion is defined as an alien entity commencing a military offensive intended to establish control over any portion of Planet Earth…
About Xenolith: The Alien Crystal plague
From the infinite depths of space comes an utterly alien plague type. Radically new gameplay, mysterious victory conditions, interstellar genes, haunting music and much more. The world will never be the same again.
Xeno-form the Planet!
Penetrate the Earth’s crust and begin a geological process to convert everything into pure, alien crystal. If any native lifeforms get in the way - simply shatter them in an unstoppable resonance cascade.
Extinction Event!
Use gravitational anomalies to pull meteors out of orbit. Choose whether to focus on crystal geodes to spread infection, EMP bursts to disrupt human technology or even vast, continent killing asteroids from deep space!
Resistance is futile
Humans are utterly insignificant but they can still disrupt you if left alone. G-COM will intelligently deploy advanced technologies including disruptors, defensive satellites, cloud seeding, alien powered computers, artificial tsunamis and more.
About Six New Scenarios
Anti-Vax
Faith in vaccines is collapsing. Global vaccination campaigns fight to hold the line, but weaponised conspiracies and viral misinformation are infecting the truth! What's the worst that could happen?
Hell on Earth
It's time to subjugate the world! Unleash a heat-loving, hell-spawned plague to corrupt people, animals and even the world itself. Satan is waiting in the depths...
Zombies vs. Earth
A melting glacier unleashes a forgotten nightmare. Greenland falls to the zombie hordes overnight! There is no virus, no cure, only the relentless march of the undead. Can they consume the world?
Measles
Measles is one of the most preventable diseases in the world thanks to modern vaccines, but misinformation and dangerous new mutations could lead to a deadly resurgence. Can you bring Measles back from the brink?
Herd Immunity
What doesn't kill humanity makes it stronger. In this upgraded simulation, infected people may now recover from diseases and develop a natural immunity to prevent reinfection. Can Herd Immunity save the world?
Cure Mania
The world’s gone cure crazy! Scientists are obsessively coordinated, sharing breakthroughs in real time across every border. Cure planes will launch earlier, and *much* more frequently. Can your disease survive when the skies are painted blue?
Special bonus for everyone: Leprosy
Good news, everyone can have Leprosy for free - even if they don’t have the new Aliens & Anti-Vaxxers DLC. To experience it first hand, just update the game and it will be there waiting for you!
Leprosy
Leprosy still infects around 200,000 new people every year due to social stigma and long incubation periods but thanks to modern medicine, it's fully treatable. Can you save humanity's oldest disease from long-term decline?
James Vaughan, the founder of Ndemic Creations said:
“I'm excited we're able to continue to update Plague Inc. with new and thrilling expansions more than a decade after release, thanks to support from our fans. Aliens & Anti-Vaxxers is far from the end of Plague Inc., we've got so many more cool ideas to bring to the game, so watch this space!"
Mobile and Console Release
The Xenolith Special Plague will be coming to Android and iOS in May, and PlayStation, Xbox and Switch later in the year.
