Casual tier list, main Easter eggs not rating them this list is for maps you can just boot up and play and get to high rounds. And have a chill time doing it
The reason I put the waw maps so low simply for the fact they didn’t age well gameplay wise, buggy zombies no pack a punch besides the giant, high rounds still aren’t that fun.

Bo1 high rounds aren’t that much fun either, weapons damage falls off hard making high rounds really slow.

Bo2 suffers from the same issue, origins made high rounds fun, motd has a good wonder weapon, good spot to train, buried is fun but camping by jug gets old fast.

Bo3 is just good all around, maps feel fun to get to high rounds, all the wonder weapons are good. Gobblegums made you able to pack on the waw maps.

Bo4 same thing as bo3 minus alpha omega and tag Der toten. Weapon weapons are eh not that remarkable though tag is far more fun to play then alpha.

Cold War, all these map and outbreak you can just boot up and play and get to high rounds. None of these maps feel trash to play or put me to sleep.

Bo6 pretty much a good lineup, same as Cold War, boot up and play, the the tomb and liberty falls felt super lack luster.
