Typically, we'd expect a Call of Duty campaign to last around 7 hours. They've never been lengthy titles. The longest according to players on HowLongToBeat is Black Ops 3, the campaign of which should take players around 9 hours to finish.

Aside from reported details about 2024's Call of Duty campaign and multiplayer, it has also been reported that the game will feature its own Zombies mode. While Zombies has been a hugely successful game mode for CoD in the past, the lack of involvement from Treyarch in the upcoming title could spell disaster.

Worry not about PVP: There is a maximum of 24 players in each server, but Modern Warfare Zombies (MWZ) is a PVE-focused game mode within Call of Duty: Modern Warfare III. Work together or ignore other players entirely.
