Pathogen Zero

The world is in your hands — and in your hands it will die. Evolve your pathogen and wipe out humanity before they find the cure.

The world is in your hands. And in your hands, it will die.

Build a pathogen from a single cell and carry it to every corner of the planet. Start with a silent outbreak in one unlucky country… and don't stop until no one is left. But be careful: the moment the world notices you, the best labs on Earth race for the cure. It's you or humanity. Only one wins.

A REAL WORLD A 1:1 world map with real data for every country: population, climate, healthcare, cities, airports, seaports and borders. Nigeria doesn't play like Iceland. A rich, cold country is a fortress; a hot, crowded megacity is a powder keg.

EVOLVE WITHOUT LIMITS 13 pathogen types — Bacteria, Virus, Fungus, Prion, Bio-Weapon and lethal special plagues — each with its own playstyle. A full evolution tree: spread by air, water, blood and animals; symptoms that chain into devastating combos; and traits to resist cold, heat and drugs.

REAL STRATEGY Symptoms make you deadly… but they expose you. Kill too fast and you'll speed up the cure. Hide too long and you'll kill no one. Every game is a knife-edge between stealth and aggression, with decision events that change everything. And yes — even on Normal you can lose if you play badly.

MASTER IT A final score and letter grade (can you earn the S?), achievements, special scenarios and difficulties up to Mega Brutal. Easy to learn, brutal to master.

No ads. No nonsense. Just you against 8 billion people.

How fast can you wipe humanity off the map?
