Uncharted 3: Drake's Deception has just been brought up to version 1.05 with the release of the new "Flashback Map 2" DLC. In addition to adding support for the DLC, the new update comes with some bug fixes.
Integrated bandwidth testing for hosts, so only hosts with optimum connections will be permitted to become game hosts (will help improve gameplay experience for everyone) Fixed an issue in which, under some circumstances, some players of a party would be left in the lobby while others went into Matchmaking and played matches Medal fixes for Fort – Adventure Mode specific medals; all medal icons now show up appropriately and medals can be obtained in-game.
The patch will be automatically downloaded when you start up Uncharted 3 as long as you're connected to the PlayStation Network on your PS3.
