The Last of Us is an action-adventure video game series and media franchise created by Naughty Dog and published by Sony Interactive Entertainment. The series is set in a post-apocalyptic United States ravaged by cannibalistic humans infected by a mutated fungus in the genus Cordyceps. It follows several survivors, including Joel, a smuggler who lost his daughter during the outbreak; Ellie, a young girl who is immune to the infection; and Abby, a soldier who becomes involved in a conflict between her militia and a religious cult. The games use a third-person perspective in which the player fights against hostile humans and cannibalistic creatures with firearms, improvised weapons, and stealth.
