Since then, it has made its way into most Call of Duty titles with a few exceptions, tasking teams of gamers to join together, build barricades, level up their weapons, and fight off hordes of zombies which increase in amount and ferociousness with each level. It's huge amounts of fun and definitely has its diehard fans.
It was also popular in Call of Duty: Mobile, the handheld version of the game, however, it was taken out in March of last year and hasn't been seen since.
Since its removal, fans of the game mode have been clamouring and the developers have been largely tight-lipped other than vague suggestions that it wouldn't be gone forever.
However, that isn't the case anymore. Screenshots from a recent Chinese beta revealed that Zombies was returning to the game, in that region, and that information light a fire under those diehards and finally the developers have broke cover, in a developers blog, and stated that Zombies is set to return to Call of Duty: Mobile "later in the year".
When will Zombies return to Call of Duty: Mobile?
While Zombies will reach Chinese gamers "soon", other regions will have to wait and it could be longer than it first seems with this announcement.
There are two reasons for this.
First, the version of Zombies that has made it into the Chinese version is the same that was in the game back when it was introduced in November 2019 featuring the "Shi No Numa" map.

When the developers have spoken about re-introducing a Zombies game mode it has always been made clear that it would look, and play, very different to what had come before.
"We wanted to see the reception, see the feedback, and see how we can potentially shape the mode for the future," wrote the developers back in March 2020. "However, the mode just didn’t reach the level of quality that we desire."
It's a point they re-iterate in their most recent statement.
"For the rest of the world, we haven't forgotten about you! Hang tight a bit longer Call of Duty: Mobile players -- we are planning to release a new ZOMBIES experience later in the year."
So the version of Zombies we see in the Chinese version is not what will be released globally and it could be a while yet until we see it return.
