Activision has detailed what to expect from the upcoming mode, and squads can be formed regardless of whether players are using PlayStation 4, PlayStation 5, PC, Xbox One or Xbox Series X/S.

In a detailed blog post, the company said: "Just like Multiplayer, squads in Zombies can be formed across platforms and generations, marking the first time in franchise history this co-op mode is available via cross-play."

Activision teased that newcomers to the franchise - and long time players - will be able to sink their teeth into the 'Cold War' take on the 'Call of Duty' staple.

They continued: "This four-person co-op mode is set to take veterans and newcomers alike on a bold and terrifying journey that expands on an iconic part of the Call of Duty franchise.

"Long-time fans will likely find something familiar with this new chapter, but that's for players to discover on their journey...

"What's canon is canon, but... with Black Ops Cold War, Zombies is starting fresh with a new narrative and a - shall we say, new? - cast of characters.

"The mode includes new ways to progress, classic fan-favorite Perks, and an arsenal of Cold War weaponry that will help survivors dominate the legions of undead."
