Modern Warfare Patch 1.17 introduces the mode alongside a slew of fixes and tweaks. Besides Warzone and the addition of a new weapon in the VLK Rogue, the update brings changes to mission challenges and objectives, enemy AI, and perk damage, among other things. 

Unlike the series’ previous battle royale mode, Blackout, which launched as part of Black Ops 4 and could only be played by those who purchased the full game, Warzone is free-to-play. It is a standalone experience and can be played independently of Modern Warfare.  

PlayStation owners can play Warzone without a PlayStation Plus subscription, though Xbox One owners will need Xbox Gold Live to play.
