The Last of Us is a survival horror action-adventure game developed by Naughty Dog and published by Sony Computer Entertainment exclusively for the PlayStation 3. It was officially revealed on December 10, 2011 during the Spike TV Video Game Awards and released worldwide on June 14, 2013. It was released in Japan on June 20, 2013. The player takes control of Joel (voiced and motion captured by Troy Baker), who is trekking across a post-apocalyptic United States in 2033, in order to escort the young Ellie (voiced and motion captured by Ashley Johnson) to a friendly resistance group, the Fireflies. The player defends the characters against zombie-like creatures infected with the cordyceps fungus, as well as hostile humans such as bandits and cannibals, employing the use of firearms and stealth aided by capabilities such as a visual representation of sound in order to listen for locations of enemies. The player can also craft weapons or medical items by combining items scavenged in the world.
