In the original Haitian version of zombification, someone is knocked out with drugs, reanimated, and then mind controlled by a voodoo witch doctor who has made his victim believe he was dead. In George Romero’s Night of the Living Dead, people rise from their graves after being exposed to radiation and slowly shuffle around, searching for brains to consume. In more recent interpretations, such as 28 Days Later, a viral pandemic infects living people, turning them into fast–moving, flesh-eating psychopaths. Even more recently, such as in the video game The Last of Us, humans are zombified by a parasitic fungus.
