Future DLC for The Last of Us and The Last of Us Remastered will be multiplayer only.
Perhaps most interestingly, Sony said it is planning "additional add-on releases" for the game later this year, and that DLC will be cross-buy between PS3 and PS4.
Following the announcement, Naughty Dog community strategist Arne Meyer told Digital Spy that the studio is "definitely not" making more campaign expansions.
"We just wanted to say when we released the Remastered version, that we weren't going to stop supporting both the PS3 and PS4 versions.
"We do have some DLC planned, it'll be multiplayer focused. We're not ready to talk about the details yet, but throughout the rest of the year we'll have some DLC drops."
As previously confirmed, the PS4 game will ship with the Abandoned Territories and Reclaimed Territories multiplayer DLC, as well as the Left Behind campaign expansion.
While by default the title runs at 1080p and 60ps, it was also revealed this week that players will be able to lock the frame rate at 30 frames per second.
Additionally, the game will include a new Photo Mode similar to the one in Infamous Second Son, which will be available via a day one patch.
Sony announced a The Last of Us Remastered release date of July 29 at E3 in June.
