It's not whether they'll die, its a matter of how they will die. Evolve a virus and take over the world.

In this disturbing game, choose whether to be a virus, bacteria, or a parasite. The goal is to spread across the world and destroy all life. The catch - humans have a strong will to live, and will struggle with every last dying breath to find a cure. So pick your evolution path wisely, and good luck killing.
