This month at PAX Prime, Naughty Dog showed off the riveting, behind-closed-doors E3 trailer of The Last of Us. If you weren't at either event, you can now see the full 16-minute demo here. We promise you it was worth the wait.

I only saw the public demo Naughty Dog showed for The Last of Us at E3, so this one was completely new to me, and serves as a stark reminder for why PS3 owners are so excited for the game. While the environmental puzzles look like standard fare, Naughty Dog has done a remarkable job of humanizing Joel and Ellie's enemies, which makes the already visceral combat even more brutal.

I'm still amazed at how dynamic all of the animation seems – we'll have to wait until we get our hands on the game to see just how orchestrated these live demos are, but so far the game is looking great.
