A very short teaser has been released with Nathan Drake treading in snow. The exclusive print reveal will be publish in Game Informer (no surprise there) with their January issue.
"Nathan Drake returns with a whole new adventure which revolves around the 13th century explorer Marco Polo and his voyages. The new Playstation 3 title will add a free climbing mechanic and stealth gameplay. Players can also expect all-new locations, characters and a focus on the game's story." (quote from Game Informer)
The January issue of Game Informer will also include the first information on Guitar Hero: Metallica.
