Naughty Dog has confirmed that the DLC expansion will add features from Uncharted 2: Among Thieves' multiplayer, including The Lab and Elimination Mode.
The Lab introduces a range of new customisation options to competitive multiplayer contests. The Uncharted 3 edition will launch with a T-bolt/Pistole-only game type, with more modes to be added in the future.
Elimination Mode splits players into two teams of five and pits them against each other. Unlike in Deathmatch Mode, players do not respawn once they have been killed.
Patch 1.11 also adds a range of other tweaks to the game's mutiplayer modes, such as the return of Message of the Day and a fix to ensure that the Game of the Year edition works with previously released DLC. A full list of the update's contents is available on the PlayStation Blog.
Uncharted 3: Drake's Deception was released for PlayStation 3 in November last year.
