Bell, We've Got A Job To Do

Reqiuem Team is headed into Vietnam with Firebase Z, a location that features heavily in the weirder parts of Black Ops Cold War's campaign.

The Dark Aether storyline appears to be happening both independently and alongside the latest story and the move to Vietnam raises some interesting questions.

Alongside the Dark Aether outbreak and portals, will we see any more MK Ultra-esque mind games?

If Treyarch were able to combine the mind-bending gameplay of Black Ops Cold War's single-player story with the chaos of Zombies, this could be one of the best COD Zombies maps in history!

Update Pre-Loading

If you're on a Playstation 4 or Playstation 5, you can start to pre-load the Firebase Z update for Black Ops Cold War.


To do this, all you need to do is "Check For Update" while selecting the Black Ops Cold War application.

Alternatively, starting the game should trigger the download. However, it won't stop you playing due to the fact that it isn't live yet!

Are you looking forward to heading into Firebase Z?

Firebase Z Update Size

Reports are beginning to come out identifying the Firebase Z update's file size as pre-loading is now available on Playstation consoles.

The next update for Black Ops Cold War is weighing in at around 9GB. This might only be confirmed for PS4 and PS5, but we would expect Xbox consoles and PC download sizes to be similar.

The update goes live at 7 AM GMT on February 4th.


Firebase Z Trailer with Developer Insight

Treyarch has released a brand new Firebase Z trailer with gameplay footage and the map's developers giving some insight into what players can expect come launch day.

With this in mind, it can be assumed that Firebase Z will go live in Black Ops Cold War around 18:00 GMT on the day of release.

It is worth noting that there will be a title update available prior to this that must be downloaded in order to play the new content.

New Perks, Wonder Weapon & More

Firebase Z isn't just a map; it's a whole treasure trove of additional content.


Tombstone Soda is coming to Cold War Zombies as a new perk with Firebase Z. It will have its own Perk Machine in Firebase Z and be available via Der Wunderfizz on Die Maschine.

The R.A.I. K-84 is the new wonder weapon that will be available while playing Firebase Z. This is expected to act as the map-specific wonder weapon and shouldn't be replacing the Ray Gun.

Firebase Z will also feature new Special Enemies and could hint further at the future of the Dark Aether storyline and what's in store!

Firebase Z is launching February 4 and should be available around 18:00 GMT.
