Grounded: The Making of The Last of Us, a documentary which promises to delve deep into the creation of Naughty Dog's hit PS3 game, is now available to watch free of charge on YouTube, Sony Computer Entertainment has announced.

Created in partnership with Area 5, Grounded is a 90 minute film which should help answer some of the questions fans still have, even after playing through the recent Left Behind DLC.

Naughty Dog community strategist Eric Monacelli warns that you should probably play the game before watching the documentary, or risk spoiling what many believe to be the game of 2013.
