The development team at Naughty Dog has released the hugest patch to date for Uncharted 3 with this patch, patch 1.13. The patch adds a ton of new features and trophies for all of us to work towards.
A new tournament/arena mode, unlock-able heads, and a direct connection to weekly download-able content are all part of the massive update. Players will also be given the opportunity to use real world cash for in-game transactions, if you don't feel like doing the requisite grinding.
Still no word on when The Last of Us is going to drop, but this patch will scratch the itch until we get our hands on a whole new Uncharted game.
