It brings along a story as well, one that sees you and your zombie-battling companions traveling through time, visiting the Titanic in one instance and Ancient Rome in another. You can see one story trailer above, and two more further down this page. >The three campaigns from the trailers will be available the day Black Ops 4 launches, and will feature a number of customization options so players can tweak these campaigns. Called Mutations, these options will let players change elements like zombie speed and health, weapon damage, and more.
