Uncharted 2: Among Thieves is a 2009 action-adventure game developed by Naughty Dog and published by Sony Computer Entertainment. It is the second game in the Uncharted series and was released in October 2009 for PlayStation 3. Set two years after the events of Drake's Fortune (2007), the single-player story follows Nathan Drake, Chloe Frazer, and Elena Fisher as they search for the Cintamani Stone and Shambhala while battling a militia led by war criminal Zoran Lazarević.

Naughty Dog, LLC is an American first-party video game developer based in Santa Monica, California. Founded by Andy Gavin and Jason Rubin in 1984, the studio was acquired by Sony Computer Entertainment in 2001. Gavin and Rubin produced a sequence of progressively more successful games, including Rings of Power and Way of the Warrior in the early 1990s. The latter game prompted Universal Interactive Studios to sign the duo to a three-title contract and fund the expansion of the company.
