Uncharted 4: A Thief's End is an action-adventure game developed by Naughty Dog and published by Sony Computer Entertainment. It is the fourth main entry in the Uncharted series, and was released in May 2016 for PlayStation 4. In the game, players control Nathan Drake, a former treasure hunter who is coaxed out of retirement by his estranged older brother Samuel, who along with longtime partner, Sullivan, search for clues for the location of Henry Avery's long-lost treasure. A Thief's End is played from a third-person perspective; incorporating several platformer elements to advance the narrative, players also use firearms, melee combat, and stealth to combat against hostile enemies, as well as solving puzzles. Players navigate the game world on-foot with a grappling hook and on vehicle. In the game's online multiplayer mode, up to ten players can engage in co-operative and competitive gameplay on maps resembling the single-player environments.
