Word of Uncharted: Fight for Fortune leaked earlier this month thanks to a couple of prematurely posted content rating, but Sony now has the PlayStation Vita game officially confirmed for a December 2012 release. A PlayStation Blog post describes it as "an action-adventure turn-based card game featuring the heroes and villains from the Uncharted universe."
Personally, I had kind of hoped that the "casino/card game" descriptor from the earlier ratings leak meant we were getting some kind of Uncharted-themed casino game. Alas, that isn't the case. Fight for Fortune seems to instead take a page from Magic: The Gathering, with both campaign and asychronous multiplayer options. Check out the announcement post at the source for a more specific rundown of how the game works.
