The latest update for Call of Duty: Black Ops 6 added an expensive crossover with the Teenage Mutant Ninja Turtles, but that's not the only '90s reference in the update. (Yes, I know the original comic is from the '80s, but the CoD versions are clearly based on the movies/cartoon, work with me here.) As spotted by CharlieIntel, hidden in the skater-themed Grind map (a remaster of a map from Black Ops 2) is a poster with a Tony Hawk's Pro Skater logo and the date March 4, 2025.
