There won't be a campaign in Call of Duty: Black Ops 4, but the studio will have three separate Zombies experiences for players to play at launch. The first experience that Treyarch unveiled is called "IX," which starts a brand new storyline that has players battling against an ancient order in a Roman battle arena. The second (also starring the new cast) is called "Voyage of Despair," which takes place on a luxurious cruise ship - perhaps the Titanic, which means players will be traveling through time. Finally, the narrative that previous Zombies modes have told, the Aether story, will continue in a map that is being called "Blood of the Dead."

Debuted as a bonus feature in 2008's Call of Duty: World at War, Zombies quickly became a staple of Activision's popular first-person shooter. The cooperative multiplayer mode finds four players working together in order to survive waves of zombies. While it was always a bit surreal (it started off as battling Nazi zombies), the mode has continually gotten more ridiculous in recent years as giant robots and time travel have gotten involved.

Besides the "Blood of the Dead" mode, Call of Duty: Black Ops 4 will serve as a new start for the Zombies mode. Lead writer Craig Houston came on stage during the reveal of "IX" and told fans that Black Ops 4 "marks the beginning of a brand new [Zombies] storyline, separate and distinct from the Aether story." It's set to be "a new world, with new characters and new enemies." You can watch the trailer for "IX" above; the "Voyage of Despair" and "Blood of the Dead" trailers are below.

It's not just a new story, though, as Black Ops 4 is also making core changes to how players can play the Zombies mode. For the first time ever the mode will be customizable, allowing players to tailor the game to what they want it to feel like. There'll also be multiple difficulty levels, and a new Zombie Rush selection which is a simplified version of what players have come to expect. Additionally, Treyarch will be adding in seasonal events titled Callings.

All three Zombies experiences in Call of Duty: Black Ops 4 look like interesting ways to play, and Activision appears to be making some fantastic quality of life moves. Difficulty modes and customization was long overdue for the series, and it should open up the complicated mode to a larger audience than ever before. The most exciting announcement from the reveal was the Black Ops 4 battle royale mode, but this shouldn't be overlooked.
