According to Battlefield Labs players, the update also brought with it some files with references to a battle royale game mode.
Electronic Arts' Andy McNamara says the team is "focused on" Battlefield Labs, but "the community will know when the reveal is coming."
The multiplayer shooter has seen quite a bit of a resurgence in terms of players numbers for the Steam release in recent times.
Star Wars Battlefront 2 has been seeing a steady rise in concurrent player numbers since earlier this month, and the devs are excited.
This change would, for example, allow a medic to avoid frontline combat by letting them use a sniper-rifle and maintain distance.
Eight years after its rocky launch, Star Wars Battlefront II has evolved into a vastly improved and fan-appreciated experience.
The primary purpose of the 72-hour one-time-only playtest will be to test the performance of Battlefield 6's pre-alpha servers.
The next entry in the shooter franchise will be "a pivotal step in delivering on our next generation of blockbuster entertainment," EA says.
Classic movement options like crouch sprint, combat dive, and landing rolls are also making a comeback in the Battlefield Labs playtests.
The first playtest as part of Battlefield Labs will take place for two hours and will be focused on the PC version of the game.
Electronic Arts has confirmed that the next entry in its flagship shooter franchise will arrive between April 1, 2025 and March 31, 2026.
Sign-ups are available now for the testing initiative, which will see the community play a "key role in the future of Battlefield."
Electronic Arts could announce the return of the Battlefield CTE with potential playtests for the next title's multiplayer component.
It's claimed that the upcoming shooter will tout caliber-based destruction, with different caliber weapons causing different levels of damage, similar to Rainbow Six Siege.
"We don't have anything to announce, but is there a world? Sure. We love them as partners. They've been great to us," says EA"s Vince Zampella.
After World War 1, World War 2, and futuristic settings in recent years, with its next instalment, the Battlefield franchise will be returning to a modern-day setting.
"Classes are kind of at the core of Battlefield, and we're going back to that," series series boss Vince Zampella.
"We have brought together the very best team coupled with the resources and technology they need to deliver an epic Battlefield experience," says EA CEO Andrew Wilson.
The new mode, dubbed Outbreak, will see players taking on hordes of undead enemies when it goes live next week.
The titles and their DLC will be unavailable on digital storefronts from that date, while online services will end on November 7th.
