Call of Duty's Zombies mode has been one of the most consistent highlights of the franchise since its introduction all the way back in 2008's World at War. With an incredibly simple premise and general gameplay loop, but plenty of in-game upgrades, weapons, and strategies, Call of Duty's Zombies mode has managed to remain both accessible and replayable. That being said, the last few Call of Duty Zombies modes haven't offered the type of experience that fans originally fell in love with, and while it's nice to see developers try to experiment with the mode, it's much nicer to see Call of Duty: Black Ops 6 return Zombies to its roots.
