'Call of Duty: Black Ops Cold War' Zombies Firebase Z Story and Perks Revealed for 115 Day

Call of Duty: Black Ops Cold War Zombies gets Firebase Z on February 4, and a new blog post reveals what to expect from the map in terms of its story, perks and environment. The news arrives courtesy of Treyarch, who opted to use the post as a way to celebrate 115 Day.

As discussed in a blog post published on Wednesday, Firebase Z takes squads to another Dark Aether outbreak site officially referred to as Outpost 25. Those who've been there, however, affectionately call it Firebase Z. After squads dealt with Poland's Dark Aether outbreak in the previous map known as Die Maschine, this new map is set in Vietnam with new perks, characters and a previously unseen Wonder Weapon.

The arms race between Requiem and Omega Group continues. Unfortunately, however, Omega has pulled ahead with a new research post that allows them to harvest Dark Aether directly from the source. Following the capture of Agent Maxis, Weaver is tasked with infiltrating the aforementioned outpost to rescue his ally.

One major addition to the map is the Tombstone Soda perk. Reworked from its incarnation in Black Ops II, this version allows players to become a shadow with their own set of deadly weapons. Die in this form, however, and you're gone for good. Invest enough Aetherium Crystals into it, and you'll be able to regenerate health, last longer when downed and leave behind a stash with your collected equipment after you perish. If that's not enough firepower, the Napalm and Artillery Scorestreaks can be added to loadouts as well. All these features will also make their way to Die Maschine on February 4.

Today's new Firebase Z details were revealed as a part of Treyarch's 115 Day plans. For those not in the know, 115 Day is a de facto holiday for the Call of Duty Zombies community, and it's in reference to Element 115. Element 115 reanimates the dead cells used to create most of the zombies seen in Call of Duty Zombies. Keeping its amounts balanced is also responsible for holding the fabric of the Call of Duty Zombies universe together. The complex lore of Zombies wouldn't exist without Element 115, so fans take January 15 as an opportunity to appreciate the multiplayer mode that has brought them so much joy.

As far as Zombies reveals are concerned, the content for 115 Day 2021 was pretty substantial. Treyarch is the steward of all things Zombies, so what better time would there be to celebrate the launch of a brand-new map?

It's also worth noting the debut of Firebase Z marks the first time in Zombies history that a DLC map will be offered to all players of a main game for free without the purchase of a Season Pass. Black Ops Cold War Zombies stands to gain lots of fans over the coming months, and Firebase Z will be at the center of it all.

Call of Duty: Black Ops Cold War is available now on PS5, PS4, Xbox Series X/S, Xbox One and PC.
