Uncharted 4: A Thief's End is a 2016 action-adventure game developed by Naughty Dog and published by Sony Computer Entertainment. It is the fourth main entry in the Uncharted series. Set several years after the events of Uncharted 3: Drake's Deception, players control Nathan Drake, a former treasure hunter coaxed out of retirement by his presumed-dead brother Samuel. With Nathan's longtime partner, Victor Sullivan, they search for clues for the location of Henry Avery's long-lost treasure. A Thief's End is played from a third-person perspective, and incorporates platformer elements. Players solve puzzles and use firearms, melee combat, and stealth to combat enemies. In the online multiplayer mode, up to ten players engage in co-operative and competitive modes. Development of Uncharted 4 began in 2011, soon after the release of Uncharted 3. It was led by creative director Amy Hennig and game director Justin Richmond. Development was hampered in 2014 due to Hennig and Richmond's departure from Naughty Dog; they were replaced by Neil Druckmann and Bruce Straley.
