Call of Duty: Warzone is getting full integration with Modern Warfare 3 at the arrival of Season 1 on December 6. The big update includes the battle royale’s new Urzikstan map, but the seasonal blog post announced that DMZ will remain playable without any new content or progression. Here’s everything you need to know about the future of Warzone’s extraction mode.

Warzone’s free-to-play DMZ extraction mode will remain available to access through the Warzone section of CoD HQ app. DMZ will continue to be fully playable across all existing maps, including Al Mazrah, Ashika Island, the Koschei Complex, Building 21, and Vondel. Additionally, all existing missions will continue to be available.
