Announcing Aliens & Anti-Vaxxers and Update 1.23

Plague Inc: Evolved · published 26 Mar 2026, 14:38 UTC

All newsPlayers around this dateRead on Steam

From the infinite depths of space comes an utterly alien plague type, we bring you…

Xenolith: The Alien Crystal plague

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. 

New Scenarios

But that's not all! New scenarios are coming with this new DLC…

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?


and more!

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.

The free update 1.23 will launch at the same time for the base game. 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?
