Vanguard will feature a new Call of Duty Zombies mode by Treyarch

With that said, adding Treyarch's Zombies entries to Vanguard is good news for fans who've been following the mode's narrative.

According to Activision, Treyarch's Zombies mode for Sledgehammer will fit right into the game's timeline. Instead of following up on the events of Black Ops Cold War Zombies, Vanguard will tell the origin story of the Zombies mode. Activision added that this new Zombies mode for Vanguard will tie directly into the Zombies mode for Black Ops Cold War. What's next for Call of Duty: Vanguard? As promised earlier, Activision went ahead and revealed Call of Duty: Vanguard on August 19. The game's full reveal gave audiences a glimpse of what to expect from the latest installment in the Call of Duty franchise. This includes information about the single-player campaign, which will star four distinct soldiers from around the world banding together to form a new special forces team for World War 2.

In addition, Activision also revealed that Vanguard will have a new multiplayer mode and up to 20 multiplayer maps available at launch.

If Activision continues with its current path, next year's collaboration will include even more of its multiple Call of Duty studios. We might see Treyarch continue the Zombies narrative with the next Call of Duty game and a campaign from Infinity War with Raven Software working on the multiplayer.
