The people have spoken. The people, it turns out, would like anti-vaxers to be added to Plague Inc, an infect ’em up inspired by (well, copied from) hit noughties flash game Pandemic. You play as a disease attempting to eradicate humanity, like a viral incarnation of Nickelback*. Anyone who says Change.org never has a meaningful impact on the world is a fool.
Developers Ndemic Creations have heard your cries, and announced a special scenario involving anti-vaxers. An easier one, presumably.
