Naughty Dog details Uncharted 2 DLC
It appears Uncharted 2 will have a lot of post-release back up as Naughty Dog Multiplayer Designer Justin Richmond confirming they will be working on DLC for a while.
While speaking to Sony’s London HQ: "There will be downloadable content, yes."
"What you'll probably see is more of the competitive type: more maps, more modes, stuff like that. The co-op stuff is hugely time-intensive and the size of it - the physical download size - is huge, so that's probably not an option."
"I'm not going to say never," he added, "but for the foreseeable future we're not going to be doing that."
Richmond also came out with the idea of co-op, saying he would love to add it in for the next game.
"Naughty Dog does a really good job of defining things, and I think no one's really done a definitively amazing co-op experience and I think we can do that, and it's something that at some point we'll tackle, If I have my say, then that's what we'd do."
Uncharted 2 is hitting retail shelves on 16th October for the Playstation 3
