I have been playing zombies since BO1 released, so I figured it was finally time to make one of these tier lists. My rankings are based on personal enjoyment, including nostalgia, easter eggs, replayability, and overall map quality. For maps that appear across multiple titles, I considered all versions but only ranked the map itself once. I don't think any map here is worse than C tier, but I was never a huge fan of Dead Ops. I've also hit round 100 on nearly every map shown, so I might make another tier list ranking them by difficulty if people are interested. Based on the games I missed or didn't bother trying, are there any bangers I left out? Also what do you think of my old-head level ratings?
