Naughty Dog have blown the lid off the first Uncharted 3 DLC pack. Flashback Map Pack #1 will be a collection of multiplayer levels from previous Uncharted games, and will naturally be free to members of the Fortune Hunters Club. More details will be forthcoming over the next few days, but the two screenshots linked above give us a quick glimpse into what we can expect. The "#1" suffix heavily implies that more recycled maps will also be on the cards.
As stated back in October, Naughty Dog won't be releasing any singleplayer DLC.
In other news, a selection of Killzone-themed multiplayer skins are now available for roughly $1.49 or free to Fortune Hunters.
