Start boarding up the doors and windows now, because it seems Activision and Treyarch are preparing to unleash another batch of Zombies on the world. Back in 2017 we got Zombies Chronicles, a collection of eight remastered maps released as DLC for Call of Duty: Black Ops III. Of course, with only eight Zombies maps a number of favorites were left out, leaving some to wonder if a second collection might happen. Well, apparently, we’re in luck.

According to reliable Call of Duty and Battlefield leaker Tom Henderson, Zombies Chronicles 2 is the real deal. Per our leaker, the newly remastered maps have been in development for several years and are pretty much ready to go now, but Activision is waiting for the best strategic moment to release them. So, when might that be?
