Powered by a new version of the IW engine, Modern Warfare II continues to support cross-platform multiplayer and also features a free-to-play battle royale mode, Warzone 2.0, a follow-up to the original Warzone, all within a single cross-game launcher, known as Call of Duty HQ.

As of September 21, 2024, Call of Duty: Warzone!" Caldera will shut down, as our teams focus on future Call of Duty content including the current Warzone free-to-play experience. We all have had incredible Warzone experiences across the Call of Duty franchise since its first launch, including those in Warzone Caldera.
