Picture the most violent you can think of...
... that is a children's game compared to what I am about to describe to you.
Enter Plague Inc. No guns, no magic, you're a disease. You kill with fevers. You will with tumors! You kill with necrosis! You kill with Dysentery! You kill with zombies! You kill with brain worms! You kill with organ failures!
You kill the entire world! Billions will die by your microscopic hands. Men and women. Strong and weak. Rich and poor. Honest and deceitful. The last pitiful homosapien will die howling in agony, drowning in their own infected mucus and poisoned blood in some hole in the ground, covered in the twisted, freakish, unrecognizable remainss of what were once it's mate and spawn. You will leave the world empty, correcting the great cosmic error that was once the human race!
But don't think this will be easy. Oh no; the things will fight back. They're smart, they're rich, and they take pride in all the diseases they've wiped out in their short pitiful existance. Rich countries will put aside their differences and work together to add you to the tally of ailments they've purged from this planet. But for all their wealth and knowledge, even the scientists and doctors that they hide behind are still susceptable to you!
This is Plague Inc. The fun little game of human extinction or enslavement.
And it's the nastiest out there!
