Sony has lifted the lid on the sequel to its PS3 action-adventure, Uncharted: Drake's Fortune, via a trailer and a Game Informer magazine cover.
Uncharted 2: Among Thieves "revolves around the 13th century explorer Marco Polo and his voyages", according to Game Informer's teaser.
The magazine also says that "free climbing" and stealth will be the major gameplay additions to the third-person adventure from the Jak & Daxter developer, Naughty Dog.
A short teaser trailer has also been released, showing hero Nathan Drake struggling through a snowy landscape to retrieve some kind of ancient artefact. Going by this and the cover, Uncharted 2 will swap the first game's steamy jungle for a cold, mountainous setting.
We can expect more detail when Among Thieves gets its "world premiere" a week on Sunday - December 14th - at the 2008 Video Game Awards.
