Rumors about an expansion for Naughty Dog's "Uncharted 4: A Thief's End" continue to appear, after another source claimed that the game developer is gearing up for the DLC's release before the end of the year.

Express UK first talked about the possibility of seeing a new DLC for "Uncharted 4" in the upcoming PlayStation Experience event that will be held in Anaheim, California on Dec. 3. But a new report from Let's Play Video Games mentioned that "Uncharted 4" voice actor Troy Baker almost confirmed that a story expansion will definitely come out for the game soon.

The publication reportedly caught up with Baker during the MCM Comic Con in London. While he might not have given a direct answer when asked about the rumored DLC, the voice actor revealed that it will be formally announced "very soon." The actor also claimed that the upcoming "Uncharted 4" DLC could possibly be "by far the biggest story DLC [Naughty Dog] have done."

The report also mentioned that the plot of the rumored DLC could have something to do with lead character Nate Drake (voiced by Nolan North) and Baker's character, Sam Drake. However, the plot will not include Nate's daughter, Cassie.

But while waiting for the release of the rumored "Uncharted 4: A Thief's End" DLC, the game developer recently announced that they already rolled out a beta testing for the game's multiplayer option.

According to PlayStation Lifestyle, the multiplayer beta test playlist will run from Wednesday, Nov. 3, until the weekend. It will allow players to sample the game's Classic Mode, which is described as "a back-to-basics mode that focuses on core combat and movement. There's no in-match Store, Radar, Mysticals, or Sidekicks and Heavy Weapons will spawn around the map."

The beta test playlist also comes with the game's the 1.15 patch that has several game improvements and glitch fixes.
