Uncharted: The Lost Legacy is a 2017 action-adventure game developed by Naughty Dog and published by Sony Interactive Entertainment, serving as a standalone expansion to 

Uncharted 4: A Thief's End. Players control Chloe Frazer, who seeks the Tusk of Ganesh in the Western Ghats mountain ranges of India, with the help of ex-mercenary Nadine Ross, 

and prevent a ruthless warlord and his army of insurgents from igniting a civil war in the country. It is the first Uncharted game not to feature series protagonist Nathan Drake. 

Like other Uncharted games, The Lost Legacy is played from a third-person perspective; players use firearms and can use melee combat and stealth to defend against enemies.

 Players solve puzzles, incorporating several platformer elements to advance the narrative, and navigate the game world on foot or by vehicle.
