Uncharted 2: Among Thieves will be about 40 percent puzzle-solving and 60 percent action, but developers Naughty Dog hope you don"t notice that.

What they want you to notice instead is the pacing of this second entry in the franchise, that the action is more tense, the exploration more seamlessly integrated into the title and the puzzles more subtle.

"I think gamers are going to notice that it"s going to be a little more action packed," said Naughty Dog spokesman Arne Myer. "There"s a little more tension, a little more action behind everything (Nathan Drake) does."

Naughty Dog tried worked to create a game that is much bigger than the first title, one that has broader scope and a better sense of scale.

Meyer showed off a new level to press attending a behind closed doors meeting with them during this week"s Gamescom in Cologne, Germany.

In it Drake has been sent to snowy mountains where he has to work with a Tibetan guide to find a hidden temple in an ice cave.

"We"ve been showing off a lot of action," Meyer said. "In this section we wanted to change it up a bit and show a bit of exploration and puzzles."
