BO3 hands down, the maps and mechanics were peak. Origins still goated. Cold War zombies hit different with the loadouts and the vibe. Easier to jump in and grind.
BO1 had that classic creepy energy, Kino der Toten forever a banger. Nostalgia maxed.
BO2 zombies was fire too with all the story stuff and wild maps. Transit was chaos but kinda fun.
Vanguard zombies? Yeah we don’t talk about that mess. That one was dead on arrival fr.
