Sony has released a decent chunk of gameplay footage from Naughty Dog's The Last of Us. The Uncharted studio showed off the 16 minute movie below at PAX Prime over the weekend, having previously screened it for select media at E3. Naughty Dog community strategist Eric Monacelli says: "This demo highlights narrative exploration through interactive prompts, environmental puzzles, the balance of power AI, and some of the dynamic stealth elements you'll be able to use to plan Joel and Ellie's survival. "How many resources are at your disposal? Do you go offensive or defensive? You'll have to keep calm, think, and rely on your partner, Ellie, as you survive and make your way westward." Sony has confirmed that The Last of Us release date is set for 2013.
