Call of Duty Zombies has had its ups and downs over the years, with fans divided over the latest iteration in Modern Warfare 3. Ultimately, various parts of the Call of Duty community seem to want something different from the mode, whether it be a focus on storytelling, prioritizing Easter egg content, innovating like with MWZ, or going back to simple survival gameplay. This likely has to do with how much Zombies has evolved over the years, as most of its maps and modes tend to be unique in some way. While this variety ensures that rankings will often come down to personal preference, it is possible to at least sort the maps into wider categories via a Tier List.
