The third installment in the PS3 exclusive Uncharted series will hit stores sometime in 2011 - while a motion picture adaption featuring Mark Walhberg is shooting - and is shaping up to be the talk of the town.

Focusing around Drake's relationship with Sully, Uncharted 3 is looking to delve deep into personal issues of trust (among other issues) centered around a tasty theme of deception. Adventuring is still the meat of Uncharted, and expect it in spades while traversing throughout the Rub' al Khali Desert searching for a fabled city buried in the sandy terrain. Bringing the desert to life is a challenge that Naughty Dog is tackling head on. 

"When we first came up with the idea of sand, you see everyone's eyes light up here and go, 'Yeah, that's going to be really hard — let's do it!'" said the game's creative director Ann Henning. 

Additional features include giving Drake the ability to climb backward, as well as to fight multiple people simultaneously. Naughty Dog is also aggressively tweaking the multiplayer system to play a bigger role in the third Uncharted installment.
