Warzone Season 4 is here, and the new update introduces a ton of new content and multiple weapon buffs and nerfs to Call of Duty’s battle royale. Here are the full patch notes for Warzone’s big seasonal update, including the additional changes added on June 4.

Starting with maps, Warzone Season 4 changes the way Bunkers work in Urzikstan, and Gulag now has more silos for 1v1 battles. Additionally, Buy Back Royale Solos returns with this update, with more modes following as the season progresses.

Midway through Season 4, a public event named Runaway Train will drop, aiming to change up the end-game meta. Speaking about the meta, we’re also getting a bunch of weapon buffs and nerfs, which should change up which Assault Rifles, SMGs, and Snipers you’ll want to be using.

While our teams are targeting to release Ranked Play Battle Royale before the end of the year, we are not ready to commit to specific timing just yet. We are using the months ahead to fine tune the design of our Ranked Play system to reflect and compliment changes since made to the core Battle Royale experience.

In the interim, we are committed to maintaining a robust competitive scene on our larger map through the ongoing World Series of Warzone program. This program ensures that players continue to have access to high-stakes opportunities as we prepare for the return of Ranked Play Battle Royale later this year. Additionally, given the success of Ranked Play Resurgence, we will continue to dedicate efforts to this mode for upcoming seasons. Our goal is to continue to provide a diverse and fulfilling competitive experience across different modes, all while honing in on the future of Warzone’s competitive landscape.

We understand that the timeline for the return of Ranked Play Battle Royale may be longer than many had hoped. However, we are incredibly excited for the months ahead while we work on bringing this beloved competitive experience back into players hands.
