About this 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.
Control viruses in this idle simulator game!

The game is fun basically a clone of pandemic. there are ad's but they are short. in the beginning there aren't as many ad's but once you get a bit into the first level the ad's become very aggressive (one ad every 36 seconds). I'm sure you can purchase to remove ads but unfortunately I wasn't able to see how much it was due to battling ads every time I switched any tab. again it is a fun game so if you don't mind watching ad's I recommend the game. 3/5

was going well until I got to the 2nd pathogen, now that's maxed out on mutations it's stuck at 4% infection rate. no more progress to be had, can't even restart the level to try again. waste of time. so now that bug has been fixed and after getting 100% on bacteria the only thing I can do is repeat that level. it won't progress to the 3rd pathogen.....

I don't normally leave reviews on anything but this game became unplayable within 20 minutes, the sheer amount of adverts is crazy, like I'm all for ads if you want to watch to increase prize drops or speed up production but it forces ads on you less than every minute, I've had it installed for 20-25 minutes I'm leaving this review before uninstalling.
