A Call of Duty leaker has revealed in-game files that seem to suggest a new crossover between Black Ops 6 and Teenage Mutant Ninja Turtles is in the works. Activision previously collaborated with the popular Teenage Mutant Ninja Turtles franchise back in 2023 for Modern Warfare 2, but it looks like the two will be coming together once again for a new collaboration within Black Ops 6 and Warzone.
