Developer Infinity Ward will replace the Zombies mode with something else, potentially an expansion of the Survival mode first introduced in Call of Duty: Modern Warfare 3. That's according to a new report, with anonymous sources saying that Call of Duty: Modern Warfare 4 will not feature a Zombies game mode.
However, while Modern Warfare 4 may gain one type of content, it may decide to drop another. The 2019 entry in the popular first-person shooter series is expected to feature a single-player campaign after Black Ops 4 decided to ditch the mode. It has been highly rumored that the next Call of Duty game will be Call of Duty: Modern Warfare 4.
