Call of Duty: Warzone is now available on Nintendo Switch 2 through the eShop, Nintendo Life and Insider Gaming report. The battle royale is free to play, and you don't need to buy Modern Warfare 4 to access it. SourceSource
You'll need an Activision account, according to Nintendo Life. The outlet describes Warzone as separate from Modern Warfare 4's single-player, multiplayer and DMZ modes. This is free access to the battle royale, not a surprise giveaway of the rest of MW4. Source
The Switch 2 debut coincides with Season 1 of Warzone and Modern Warfare 4. Insider Gaming Brasil reports that the seasonal update integrates content from MW4 into the battle royale, including weapons and progression changes. SourceSource
One platform arrives, two leave
Insider Gaming reports that Warzone's PS4 and Xbox One servers permanently shut down on November 6, 2026, as the new season began. That's a considerably less exciting seasonal update for anyone still playing on those consoles. Source
Former PS4 and Xbox One players can retain their progress on supported hardware by using the same Activision account, according to Insider Gaming and its Brazilian edition. If you're moving to Switch 2, that's the account to bring along.
