Campaign development is in partnership with Infinity Ward. Sledgehammer is also "working closely" with Treyarch on Zombies.
The Steam page lists Infinity Ward, Sledgehammer Games, Beenox, Raven Software, High Moon Studios, Demonware and Treyarch.
Announced last year, the mobile battle royale shooter seems to have been delayed into November, based on its updated App Store page.
Beenox and Toys for Bob are allegedly developing it with Infinity Ward "leading the narrative" and Raven Software "consulting on gameplay ideas.".
The mobile battle royale will be at the Call of Duty: Next showcase, along with Call of Duty: Modern Warfare 2 and Warzone 2.0.
Since launching in 2020, Call of Duty: Warzone has had over 125 million players. Over 3,000 people are working on the franchise currently.
Currently codenamed Project Aurora, the mobile battle royale title was confirmed to be in development less than a month ago.
The title, which seems to be the Call of Duty: Warzone for mobile, currently has a limited number of participants for this phase of testing.
The new studio will open up many opportunities for Beenox to take up even more ambitious projects across the Call of Duty franchise.
Activision is hiring as it ramps up the mobile title's development, with various internal studios involved, including Solid State Studios, Beenox, Demonware, and Digital Legends.
Following reports earlier this year claiming the same, it's now been confirmed that Activision has now got all of its studios on Call of Duty detail.
Interestingly enough, the recent reveal trailer for the World War 2 shooter seems to be attempting to distance the brand from Activision, with the company in the midst of a controversial lawsuit.
Activision president Rob Kotisch recently revealed in an earnings call that a new Call of Duty mobile title is in development right now.
Developer Beenox is currently busy with Crash Bandicoot 4's N. Verted modes.
The shooter's PC version will be handled by Beenox.
Available first for PS4, the classic campaign finally comes to other platforms.
The remaster finally comes to both consoles tomorrow.
With two other titles sharing a base, it didn't make sense at this time.
It releases for Xbox One and PC on April 30th.
The end of a lengthy post-launch content schedule.
