Game Director Neil Druckmann has confirmed that there will not be DLCs coming for “The Last of Us Part 2”. Naughty dog has used DLCs and Season Passes for past games like Uncharted 4 and The Last of Us Part 1 but it seems they may be shifting away from that business model.
“With The Last of Us, I think we had some season pass or something that we said ahead of time we’d have some story DLC. No, there are no plans for DLC.” -Neil Druckmann
He is stating that the first game had planned out DLC’s prior to launch while this one has none. There are still plans to add a multiplayer mode in the future, but no details on what it will include.
