Call of Duty, developed by Infinity Ward and published by Activision, is one of the best-selling first-person shooter franchises in the world. It began as a World War II shooter but has since evolved into modern warfare, futuristic settings, and battle royale modes. One of the most popular modes in the Call of Duty series is the Zombies mode, which first appeared in Call of Duty: World at War.

The Zombies mode features cooperative gameplay where players fend off waves of undead enemies, often in elaborate and eerie environments. Over the years, the mode has gained a large following due to its challenging gameplay, deep lore, and Easter eggs hidden in each map. Call of Duty remains a dominant force in gaming, consistently breaking sales records with each new release and drawing millions of players worldwide.
