Sony have released an extended version of Naughty Dog's The Last of Us's E3 gameplay trailer which is set to release in the first half of 2013.
This 15 minute video is the same footage that was shown behind closed doors to the press at the LA based electronics expo back in June and just last weekend at PAX 2012.
Here's the synopsis from Sony:
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.
