Naughty Dog’s Neil Druckmann has teased the studio’s upcoming The Last of Us multiplayer game, saying it is the studio’s most ambitious title to date.

Speaking to ComicBook, Druckmann said Naughty Dog has been working on the title for a “long time,” specifying that work began on the project before The Last of Us: Part II was released in 2020.

“That’s the most ambitious project we’ve ever done. Expanding the world even further. Continuing to tell a story but in a multiplayer space. I won’t say too much about that,” he said.

The Last of Us: Part II was originally expected to launch with a new version of the first game’s Factions multiplayer mode. Naughty Dog explained in 2019 that the scope of the Factions mode the studio originally announced for the game grew to the point where it couldn’t be included alongside the main campaign.

The new Last of Us multiplayer game hasn’t been officially unveiled yet, though Naughty Dog has released concept art and other details. In 2023, Naughty Dog will begin to provide details on the game, which the studio said is “shaping up to be a fresh, new experience from our studio.”

Naughty Dog is known best for its single-player story games, and the studio stressed that the new Last of Us multiplayer title will be rooted in the company’s “passion for delivering incredible stories, characters, and gameplay.”

The Last of Us multiplayer game is one of multiple projects in development at Naughty Dog right now. The other could be The Last of Us: Part III or a new IP, or something else entirely.

On the more immediate horizon, HBO’s Last of Us TV series premieres Sunday, January 15, and reviews for the show boast that it’s an excellent video game adaptation.
