The above video, which details an alternate ending to The Last of Us, was previously only seen by those who attended Naughty Dog's panel at PAX Prime. Through the wonders of the internet, we're all now able to see it – though we stress no one should watch unless they've finished the game. Spoilers abound!
Surprisingly, this alternate ending was completely improvised. Aside from one line of direction from creative director Neil Druckmann, the actors came up with everything in the moment. It's an odd sequence, but somehow it totally works!
