Last week, Naughty Dog and SCEA held a press event at the PlayStation.Blog lounge at GDC 2011. The press event began with the first ever demo outside of Naughty Dog halls of UNCHARTED 3: Drake’s Deception in stereoscopic 3D. The real meat of the press event was the unveiling of the central antagonist that will try to foil Nathan Drake and Victor Sullivan at every opportunity – meet Katherine Marlowe in the trailer below.
