Uncharted 4: A Thief's End is an action-adventure third-person shooter platform video game developed by Naughty Dog and published by Sony Computer Entertainment for the PlayStation 4 video game console. It is the sequel to Uncharted 3: Drake's Deception, and is the fourth and final installment in the Uncharted series starring Nathan Drake,[1] as well as the last in the series to be developed by Naughty Dog.[2][3][4]. The game was released worldwide on May 10, 2016.[5] Uncharted 4: A Thief's End received widespread acclaim from critics with praise particularly given to the narrative, visuals and gameplay. Three years after the events of Uncharted 3: Drake's Deception, Nathan "Nate" Drake, now retired as a fortune hunter, has settled into a normal life with his wife Elena Fisher. His world is then turned upside down when his older brother Sam, long believed to be dead, suddenly reappears seeking Drake's help. Along with Victor "Sully" Sullivan, they embark on a race against time, across the globe, from the snow-capped peaks of Scotland to the island nation of Madagascar, in pursuit of a conspiracy behind Libertalia, a long lost pirate colony, and its fabled pooled pirate treasure. Nate must also contend with rival treasure hunter Rafe Adler, who has partnered with mercenary Nadine Ross, who owns private military corporation, Shoreline, to help him locate Libertalia. Naughty Dog outlined the game's plot as "his greatest adventure yet and will test his physical limits, his resolve, and ultimately, what he's willing to sacrifice to save the ones he loves"]. Uncharted 4: A Thief's End is an action-adventure game played from a third-person perspective. It also includes elements commonly found in platform games. The player assumes control of Nathan Drake, who is physically adept and is able to jump, sprint, climb, swim, scale narrow ledges and wall-faces to get between points, swing with a rope, use a grappling hook and perform other acrobatic actions. Drake can use various firearms such as assault rifles, pistols and grenades to kill enemies. Stealth elements are incorporated into the game, allowing the player to sneak behind enemies and kill them without being noticed.[8] The melee combat system was reworked to avoid the presence of quick time events.[9] Drake also gains the ability of controlling vehicles directly.[10]. While the game is linear, environments feature multiple paths for the player to explore.[11] Maps are also significantly larger than the previous games in the franchise,[12] with the explorable area being 10 times larger than the previous games.[13] The artificial intelligence (AI) of enemies was enhanced. They are now able to respond to the player's actions more responsively, coordinate tactics, and cooperate with each other.[9] The AI of Drake's companions, including Sam and Sully, were improved and will assist Nathan in combat situations, though the player can not directly command them.[14] A dialogue tree is introduced, though it does not affect the story's progression.[15] The transition between cutscene and gameplay sequences has been described as "seamless".[16] Extra visual filters and modes, such as a zero-gravity mode, bullet.
