Activision announced that Warzone Caldera servers will shut down on September 21, 2024. The battle royale included player progression from Modern Warfare (2024), Black Ops Cold War, and Vanguard.

It seems that all time we invested in Warzone 1 is gone for good. We don't have absolutely nothing about our wins, kills and other stats! We also lost another hard-earned things like vehicle skins, sound tracks, horns, player titles and watches that doesn't exist in Modern Warfare 2024.
