How To Pre-Load

If you own a PlayStation, you should be able to pre-load the next Call of Duty update right now.

In order to do this, all you need to do is open up the menu while selecting the Black Ops Cold War application.

From here, you can select "Check for Update" and it should initiate the download if it hasn't started already.

File Size Information


With pre-loading well underway, we now know the rough size of the Black Ops Cold War update ahead of COD Zombies' Firebase Z release.

The new patch is around 9GB in size on both Playstation 5 and Playstation 4.

There is no word yet on the file-size for Xbox consoles and PC players, although expect something similar.

The COD Zombies Firebase Z update is scheduled for release 7 AM GMT February 4th.

Firebase Z Trailer Gives Developer Insight

Treyarch have put out a brand new Firebase Z trailer with insight from the Call of Duty Zombies development team!

It features gameplay footage and gives players a great idea of what's to come on the big launch.

You can see it in action below:


New Wonder Weapon - R.A.I. K-84

Treyarch has added another Wonder Weapon to Cold War Zombies with Firebase Z.

The R.A.I. K-84 is the newest Wonder Weapon to be added to the game mode. In a tweet below, you can get a first look at what's in store.


This doesn't mean the Ray Gun won't still appear in the Mystery Box, though.

It is safe to assume that, like most other Call of Duty Zombies maps, this will replace the D.I.,E. Maschine and become the map-specific Wonder Weapon.

Below, we've listed what each Tier upgrade does:

  • Tier I - Shadow form can regenerate health;
  • Tier II - Increased downed duration to 60 seconds;
  • Tier III - On death, drop a Tombstone stash that saves your weapons, equipment, and resources.

Although Tombstone Soda won't have its own perk machine in DIE Maschine, you'll still be able to get it via Der Wunderfizz.

New Enemies

In a similar trend to DIE Maschine, Firebase Z promises to bring more than just the traditional zombies to the playing field.

Although we don't know anything officially about what these creatures are, we know that they'll be dangerous.

New Operator - Samantha Maxis?

In the Firebase Z trailer, we also got a look at what could be the next Operator coming to Black Ops Cold War.

Samantha Maxis, Call of Duty Zombies regular, features prominently in the trailer and it has many wondering as to whether she is going to be added to Black Ops Cold War as the next Operator.

SAMANTHA - Maxis is a series regular and integral to the Dark Aether Storyline.

In Black Ops Cold War, Samantha Maxis is a member of the German BND who has gone rogue in an effort to contain and control the Dark Aether spilling out into our reality.

By the looks of it, Firebase Z might finally bring her into Weaver's Requiem Task Force as an asset.

We'll make sure we keep this updated with any additional information as it becomes available.
