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 to 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. The team sought to incorporate elements of open-world gameplay, with larger levels to encourage free-roaming exploration and combat. The relationship between Nathan and Elena was central, and Naughty Dog attempted to humanize them more than in previous games. A Thief's End was released in May 2016 for the PlayStation 4. It was the first Naughty Dog game developed specifically for the PlayStation 4. The team took advantage of the hardware to process larger dynamic environments. Following its announcement in November 2013, A Thief's End was widely anticipated. The game was acclaimed by critics, who praised its gameplay, narrative, emotional depth, visuals, and multiplayer, with several reviewers finding the game a worthy conclusion to Nathan's story. Considered one of the greatest video games ever made, it won year-end accolades, including Game of the Year awards from several gaming publications, critics, and award ceremonies. With over 15 million copies sold, it is the highest-selling Uncharted game and one of the best-selling PlayStation 4 games. A standalone expansion, Uncharted: The Lost Legacy, was released in 2017. A remastered version, alongside The Lost Legacy as part of the Uncharted: Legacy of Thieves Collection, was released in January 2022 for PlayStation 5 and October 2022 for Windows.
