Call of Duty: Modern Warfare has been a massive success for Activision and Infinity Ward so far, and so it's quite likely that the game will receive significant support for quite some time (or at least until next year's Call of Duty). All of the Modern Warfare DLC maps and modes will be free, and it looks like this may eventually include the addition of the fan favorite Zombies mode to the game.
Dataminer That1MiningGuy has been digging through the Call of Duty: Modern Warfare PC files in search of what's to come for the popular first-person shooter. They discovered a file named PRESENCE/MP_ZOMBIES, indicating that Zombies of some kind could very well be coming to Modern Warfare. However, based on the file name and the fact that it appeared in a list of maps, it seems as though it may not be traditional Zombies.
It's possible that Zombies will be integrated into Call of Duty: Modern Warfare as a special multiplayer mode. Alternatively, zombies themselves could be added to the rumored battle royale mode, as Black Ops 4 had zombies in its BR as well. Of course, it's still possible that this file is referencing a traditional Zombies mode, or maybe a Spec Ops variant, but until Infinity Ward itself offers more information, we won't know for sure.
Interesting here, I do see zombies there after all :) pic.twitter.com/w43i80JF7M— That1MiningGuy (@That1MiningGuy) November 2, 2019
so I'm assuming CP_ maps are Co-Op maps while MP_ is standard multiplayer and maps that end in _GW are ground war. pic.twitter.com/Wh8S8jsvN4— That1MiningGuy (@That1MiningGuy) November 2, 2019
Prior to Call of Duty: Modern Warfare's launch, Infinity Ward denied that it would have a Zombies mode. Infinity Ward said that Modern Warfare wouldn't have a Zombies mode because it would clash with the game's attempt to be realistic. However, the studio has since pushed back against the idea that multiplayer in Modern Warfare is supposed to be realistic, referring to it as a "playground" as a way to justify its inclusion of the controversial White Phosphorus killstreak.
Whether Zombies comes to Call of Duty: Modern Warfare as a proper game mode or as a special multiplayer match type remains to be seen. There's a good chance the undead will never be added to the game at all, though, so fans should keep that in mind before they get too excited about the idea of Call of Duty: Modern Warfare Zombies.
Call of Duty: Modern Warfare is out now for PC, PS4, and Xbox One.
