Activision stated last year that the free-to-play battle royale game Call of Duty: Warzone is coming to smartphones.
Microsoft has announced that after Warzone Mobile is released, Call of Duty: Mobile will be "phased out" over time.
Interestingly, if the new title is a disappointment, we wouldn't be shocked if Activision flips its intentions and keeps COD Mobile as the series' flagship game on mobile.
