Warzone & BO6 Nov 21 update patch notes: Rebirth Island returns, Stim Shot buff, & increased XP
The latest Black Ops 6 and Warzone update introduces a new event, adds back Rebirth Island to Warzone, and gives a much-needed buff to Stim Shots.
TheHit List eventtasks players with completing a series of contracts to earn free rewards, including the Power Drill Melee Weapon, Sirin 9mm secondary weapon, Verteran Perk, and a new attachment.

On November 18, Raven Software added Rebirth Island to Warzone’s map pool. The reunion only lasted a few hours because the development team was forced to remove the map due togame-breaking lighting and audio issues.
This update addresses those issues and ensures a better experience when jumping back in.

Meanwhile, a previous update nerfed Stim Shots in Warzone, reducing the speed boost provided after using one. Raven Software listened to community feedback and buffed the tactical equipment item.
Let’s take a look at what else changed in this update.
Warzone Nov 21 update patch notes
Here are the complete Warzone updatepatch notes.
Thank you for your patience these last few days as we’ve worked to bring Rebirth Island back to the Warzone playlist! We wanted to take the necessary time to address key issues and make improvements to ensure the best possible experience.
We’ve made several adjustments to Player and Weapon XP in order to bring earn rates across different modes closer together.
“Upon the launch of Warzone, we identified a critical issue and, in response, temporarily reduced both the speed increase and the duration of Stim Shots while we worked on a solution. Our goal is to offer a meaningful speed boost with a clear upper limit, to ensure balanced and consistent combat encounters. As it stands, both Resolute and Stim Shot provide a 15% speed boost each, with their combined effect capping at 20%. This allows players to experiment with various combinations to reach the maximum impact.”
