It's been a rough few years for Call of Duty Zombies. Though Call of Duty: Black Ops Cold War's Outbreak Zombies mode brought some interesting ideas to the table, Modern Warfare 3's open-world Zombies mode learned the wrong lessons from it, delivering a rather generic, lifeless mode that lacked the identity and beloved gameplay loop of its predecessors. Thankfully, though, Call of Duty: Black Ops 6 has been the return to form fans hoped it would be.
