The timing and frequency of Warzone playlist updates can vary. Typically, updates are released every week, usually on a Tuesday or Thursday. This is when new game modes, bug fixes, and other changes are often introduced. However, it's important to note that this is not a strict schedule and updates can sometimes be released at different times. Major updates or new seasons are usually announced in advance by the game developers. To stay updated, you can follow the official Warzone social media accounts or check their website regularly.
