The Disease: Never mess with diseases. That’s what Dr. Alice Krippin (Emma Thompson) did when she genetically engineered a variant of measles as a cure for cancer, which then turned into a lethal virus of epic proportions.
Most Gruesome Symptoms: The Krippin Virus killed 90% of the Earth’s population.
Those it didn’t kill, it transformed into ‘Darkseekers’, vampiric monsters that hunt and kill humans. How Long You’d Last: If the Krippin Virus killed you, count yourself lucky – you wouldn’t want to go up against a Darkseeker.
