Uncharted 3 details seep in

News hit yesterday that Uncharted 3 was a-go, with the first details and concept art appearing online. Now Sony has stepped forward and let Naughty Dog off the leash to let slip a few details on the game's plot and gameplay.

Speaking on the US PlayStation blog, Naughty Dog Community Strategist Arne Meyer gave details about the game, as well the return of co-op and the inclusion of 3D for the title.

"UNCHARTED 3: Drake's Deception features the return of famed fortune hunter Nathan Drake and follows him through a gripping, action-packed storyline that will take you all over the world. In his search for the fabled "Atlantis of the Sands," Nathan Drake and longtime friend and mentor Victor Sullivan set off on a daring trek into the heart of the Arabian Desert.

But when terrible secrets of this lost city are uncovered, their journey becomes a desperate bid for survival that will force Drake to confront his deepest fears.

Throughout UNCHARTED 3, you'll be taken to spectacular new locations around the globe that will showcase all of the work we've taken on to take acclaimed physics, particle and visual effects to a new level.

Competitive and co-op multiplayer will return as a key ingredient to the UNCHARTED 3 package, where all of the new features we have planned will combine with our signature single-player cinematic gameplay to create a unique action-adventure multiplayer experience that can only be found in the UNCHARTED universe.

Oh, and there's one more thing - UNCHARTED 3: Drake's Deception fully supports high-resolution Stereoscopic 3D."
