A recent interview with EuroGamer confirmed that Uncharted 3 will have no single player DLC. Naughty Dog stated in the interview that they would rather spend their time working on the next sequel.
There’s a very specific reason. Whenever we sit down and think we should do some single-player DLC, someone pitches something and we realize – that’s a five hour level.
- Justin Richmond, game director told Eurogamer
Naughty dog has a fairly small team working on their game development. 90 people to be exact, compared to Call of Duty, which has a team of around 450, they are able to release multiplayer DLC and plenty of Zombie maps DLC.
