Activision is raising the minimum system requirements for Call of Duty: Warzone Mobile in November. The company says the change is needed to support new features and technology, but it will leave some players on older devices unable to access the game.

With the Warzone and Black Ops 6 Season 1 update launching nearly three hours early, here's what you need to know about the patch, including its file size and all of the new maps, modes and weapons.

Call of Duty's Season 1 update is now live in Warzone, bringing Black Ops 6 's full integration, including omnimovement, the game's full weapon pool, a classic Prestige system, and additional features. The update also quietly removes one of Call of Duty's most annoying weapons.
