Uncharted: Drake's Fortune is one of Sony's biggest guns in the PlayStation 3's holiday arsenal, and also vaunted developer Naughty Dog's first stab at making a game on next-generation hardware. The majority of Uncharted that GameSpot have seen so far has been set in the tropical jungle where Drake and friends will battle a team of crack mercenaries on their way to hopefully discovering the lost treasure of El Dorado to become rich beyond their wildest dreams. At least, that's the plan. But what else is in the game? Naughty Dog stopped by GameSpot's office recently to show off some indoor areas from later in the adventure, which proved to GameSpot that Uncharted will be much more than a simple steamy jungle romp.
