Naughty Dog's water effects went down well in the first release, Drake's Fortune, and now the developer are focussing on dynamic weather and the role that it can play in Uncharted 2: Among Thieves.

"One thing I will say is that if you've ever tried to fight an intense cover-based gun battle against a vicious enemy in the middle of a Force Ten snowstorm, then you'll appreciate how complicated the reduced visibility can make things for combatants on both sides," Richard Lemarchand, co-designer, told IGN.

"We've spent a lot of time focused on the distinctive look that snow has as it falls and is blown by the wind, and of course on the way in which Drake leaves footprints as he trudges through the snowdrifts in the Himalayan mountains that he ventures to.When he's out in the snow he'll accumulate a layer of snowflakes on his clothes and in his hair, which will slowly thaw when he gets back inside under cover."

We're really excited about Uncharted 2, which should arrive later this year on PS3.
