The original Call of Duty: Warzone is shutting down on September 21, 2023, as recently confirmed by Activision. The original Call of Duty: Warzone hit the scene in 2020 as a free-to-play experience tied to 2019's Call of Duty: Modern Warfare reboot. It was a smash hit, largely thanks to its Verdansk map and interesting battle royale innovations like the Gulag.
