If you've ever thought "needs more beer hats!" while playing the multiplayer in Uncharted 3: Drake's Deception, then the just-released v1.13 update is definitely for you. The update, which is available now, will add microtransactions for vanity items to enhance your character's look starting on August 14, 2012, though you can also unlock that stuff -- 137 items in all -- by "earning the necessary in-game levels [or] completing specific treasure sets," according to a PlayStation Blog post.
On the play side, v1.13 also adds a new Tournament System to the multiplayer in Uncharted 3. All players will receive ten tickets "per tournament period" (you can purchase more with real money), and you'll use them to buy into various online tourneys. The patch notes, listed on Naughty Dog's website, are actually quite extensive, so click the link for a full rundown of what's new.
