Black Ops 6 gets new Zombies content in the Season 4 update, including a fan-favorite mode’s return, new challenges, LTMs, and more.

While all three of the main Call of Duty modes – multiplayer, Zombies, and Warzone – share content like the Battle Pass and new weapons such as the FFAR 1 and LC10, Zombies gets its own content.

Season 4 is no exception, so here are the full patch notes of everything included in the update.

Zombies Season 4 start date & time

The Black Ops 6 Zombies Season 4 update goes live on Thursday, May 29, at 9 AM PT / 12 PM ET / 5 PM BST.

You should be able to preload the update ahead of time to ensure you can jump right in. Also, make sure you’ve finished the Season 3 Battle Pass, as you won’t be able to access it again.

Grief mode

Activision

The Grief mode, which hasn’t been seen since Black Ops 2, arrives in Season 4. Here, two teams of four must outlast each other, with the last team standing winning.

While you can’t damage the other team, you can slow them down by shooting them, body-block them, and give them major debuffs by capturing zones.

Grief takes place in smaller sections of the existing Zombies maps, and for the full breakdown, you can check out our dedicated guide.

Is there a new Zombies map?

There’s no new Zombies map in the Season 4 update, but we can still expect one more ahead of Call of Duty 2025.

Following Season 3’s Shattered Veil Easter egg, the next Zombies map is expected to be ‘Janus Towers.’ Shattered Veil ends with Richtofen leading the crew to Janus Towers, where the ether reactors are melting down. The map probably won’t be called Janus Towers, but it’s the most likely setting.
