what is Plague Tree (Vorona Cirus Treesease)?

Spread a virus by unlocking layers that boost its strength and transmission far beyond reality.

In this game, the objective is to maximize COVID-19 case numbers by progressing through layers that enhance the virus's spread and potency. Each layer unlocks new upgrades that amplify the infection's capabilities beyond real-world limits.

It sits in the Prestige / Numbers / Automation / Prototype corner of the genre. Like most idle games it runs on a simple loop — earn, reinvest, automate — but the depth is in how long that loop keeps unfolding. Expect to check in, make a few decisions, and watch the numbers climb whether you're at the keyboard or not.
