Call of Duty is one of the longest-running and most successful AAA gaming franchises of all time. Over the past several years, Activision has carefully steered the direction of the franchise with the help of Treyarch, Infinity Ward, and Sledgehammer Games to make it a live-service juggernaut. Still, the popularity of the older games is undeniable, which has caused Call of Duty to regularly lean into nostalgia and reference beloved maps of the past.
