Pathogen

Pathogen is a game about an infection inside the human body. You control a pathogen, choosing how to evolve, which organs or tissues to infect, how widely to spread and whether to hide from the immune system. Your actions affect the body's health and gradually activate its immune response, influencing the ending.

Explore and evolve

You explore the body at a microscopic scale. Evolution can turn your pathogen into many familiar kinds of pathogens, changing how it attacks and moves, as well as the conditions for different endings. The game draws much of its content from books and online information and includes science education.
