Patient Zero: Virus Simulator

Control viruses in this idle simulator game!

Patient Zero is a new global virus idle simulator where you do not just watch the outbreak — you lead a secret underground lab creating and improving dangerous pathogens. This virus game combines long-term progress with continuous experiments and evolution.

In Patient Zero, your organization works from the shadows — gathering data, testing new pathogens, and releasing viral strains into the world. While governments try to stop the pandemic, you build your own system of spread — hidden, efficient, and designed for global infection. Every choice shapes the outbreak and the fate of disease worldwide.

This hybrid idle simulator mixes strategy, simulation, and progress. Your infections continue even when you’re away, but the most important decisions remain in your hands. Patient Zero delivers the tension of a pandemic simulator while focusing on lab management and pathogen evolution.

There are currently four main pathogens, each with unique viral strains:

* Virus
* Bacteria
* Parasite
* Fungus

A new pathogen — Nanobot — is in preparation, with more viruses on the way. Develop your lab, improve your pathogens, unlock stronger strains, and accelerate every stage of viral progress.

Your pledge to control, evolve, and dominate the global infection is in your hands.
