The game is set twenty years after an outbreak of the mutated strain of Cordyceps fungus that destroyed much of civilization. The single-player story follows Joel, tasked with escorting the young Ellie across a post-apocalyptic United States, in an attempt to create a potential cure against the infection to which Ellie is immune. Players make their way through various locations, fighting against the Infected and hostile human survivors. The multiplayer lets up to eight players engage in cooperative or competitive game matches. To accommodate Remastered’s technical enhancements, Naughty Dog spent months developing the game, beginning upon the release of The Last of Us.
