The mobile battle royale offshoot reportedly generated $1.4 million in its first four days, compared to Call of Duty Mobile's $4.2 million.
Alongside the new release window, Activision has also revealed that Call of Duty: Warzone Mobile will feature the popular Verdansk map.
Announced last year, the mobile battle royale shooter seems to have been delayed into November, based on its updated App Store page.
This follows a recent statement by Microsoft that the mobile shooter is "expected to be phased out over time" following the launch of Call of Duty: Warzone Mobile.
In the long term, Microsoft wants to slowly replace Call of Duty Mobile with the upcoming Call of Duty: Warzone Mobile.
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.
Details, images, and concept art on the upcoming Call of Duty: Modern Warfare and Treyarch's 2024 instalment have emerged from a recent leak.
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.
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.
Activision recently announced that Call of Duty: Warzone 2 is in development, but it seems a mobile version of the battle royale experience might be in the works as well.
