Game description:

There is an opinion that our world has been so much contaminated by the human race and we're actually so vicious that the planet would be better off without mankind. The main hero of Plague Inc seems to share it. Sitting in his secret lab day and night, he is working on a virus that will kill the human population. And you will be helping him on this doomsday quest! Combine various pathogenic bacterias to come up with a recipe the contemporary medicine won't be able to handle. Erase our species from the surface of Earth!
