Limited-time pop culture events have become a mainstay of live-service video games, with Epic Games' Fortnite leaning heavily into brand partnerships and collaborations over the last several years. The same formula rings true for Activision's decades-old Call of Duty franchise, which has delved further into the world of sponsorships and collaborations with each new release. Last year's Call of Duty: Modern Warfare 3 saw several iconic faces and characters make their way into the game in the form of operator skins, with Black Ops 6 likely to do the same. However, a newly released trailer confirms a somewhat surprising crossover, which sees Treyarch and Activision team up with Netflix for a new Squid Game -inspired event.
