Black Ops II's Zombies mode is renowned for its complex and often cryptic easter eggs. Each map (Tranzit, Die Rise, Mob of the Dead, Buried, Origins) has a main easter egg quest that, when completed, reveals significant lore and often provides powerful rewards. These quests typically involve multiple steps, requiring teamwork and puzzle-solving. Consult dedicated Zombies guides for detailed step-by-step instructions for each map's main quest.
