The latest Black Ops Cold War Zombies update has gone live on Tuesday, August 17, with changes to the Pack-a-Punch upgrade system, grenade and equipment changes, and a secret change to the Mauer der Toten map that Treyarch confirms no one has uncovered just yet.

The August 17 update is now available to download in Call of Duty Zombies, and there’s plenty for Black Ops Cold War players to sink their teeth into.

These include a hefty cost reduction for the popular LT53 Kazimir tactical grenade, a long-awaited Pack-a-Punch update ⁠— mainly focused on how players can choose their gun camos mid-game ⁠— and a “secret” map change.


The new easter egg is hidden on Mauer der Toten, devs have confirmed.

Treyarch has buried a new Cod Zombies easter egg somewhere on the Mauer der Toten map.

On top of all the gameplay changes, Treyarch finally got its hands on the issues that have been plaguing several different Zombies elements. These included a bug breaking the Death Perception perk, multiple Outbreak World Events not triggering, jump pads failing to launch, and more.

Dexerto can confirm the update’s download size is just under 1.2GB.

Below are the full Call of Duty Zombies patch notes for the Black Ops Cold War August 17 update, which can also be found on the usual Treyarch blog.
