The Last of Us making of documentary now free to download

The Last of Us is one of the most talked-about games of last year. Chances are, after the game's haunting final moments, you've been curious to find out more about the creation of Naughty Dog's horror adventure.

Grounded: The Making of The Last of Us is a feature length documentary produced by Area 5 that goes behind the scenes of the game's development. Previously exclusive to Season Pass holders, Sony has partnered up with Amazon Instant Video to make the entire film available for free--in SD and HD.

You can add the movie to your Amazon video library here. You can watch it on your TV using the PlayStation Amazon app, of course.
