Call of Duty Zombies is arguably deeper than most zombie modes from first-person shooter games. Unlike the zombie modes in its FPS counterparts like Counter Strike 1.6 back in the day, the zombie mode in Call of Duty, which started from Call of Duty: World at War in 2009 was much more nuanced, similar to more undead-centric gameplay from the likes of Left 4 Dead. At the same time, however, the zombie mode, while bringing forth casual fun times for the community, doesn’t seem to be going anywhere lately. Much like in the Aether storyline, Call of Duty Zombies has a cycle to break.
