Pathogen Zero vs PATHOGENEER

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?

Your plan. Their pandemic. Engineer a deadly strain, plot its evolution and release it into the world. Watch infections spread across the map as your creation breaks into new hosts. PATHOGENEER puts you in control of a fictional pathogen. Shape a branching genome, adapt to new environments and discover which hosts your strain can reach. A promising start can stall at a barrier. The right mutation can open another route. MAKE IT YOURS Choose genes that shape spread, survival, resistance and host jumping. Unlock new modifications through successful infections and build a strain with its own strengths and tradeoffs. CROSS THE HOST BARRIER Begin with plants and unlock insects, birds, land animals and humans. Explore different targets and habitats as your creation finds new ways to spread. CHOOSE YOUR GROUND ZERO Pick a starting location. Climate, habitat and host conditions affect whether your strain gains a foothold or struggles to establish itself. WATCH THE CASCADE Follow infection fronts across the map, switch host layers and zoom in on the action. Make decisions during a run as opportunities and barriers emerge. BUILD YOUR NEXT BREAKTHROUGH Keep memorable strains, carry successful genes into descendants and chase a stronger cascade. Open Threads suggest a next step for your lineage. Share your specimen, a standout spread or the stats from a run you are proud of. Where will your next creation take hold? PATHOGENEER is a fictional ecology strategy game inspired by real-world environments and habitats. Its organisms, mutations and outcomes are designed for entertainment, not real-world pathogen engineering.
