With it having a cartoony and over the top style having Harley Quinn crossover seems like an obvious choice to implement into the game.
Warner Bros. Pictures shared a short clip showing off part of the film’s cast including Harley Quinn herself Margot Robbie while they were attending an event for the movie in Hollywood.
While nothing has been confirmed it seems that the event will be a crossover to promote the upcoming film Birds of Prey: And the Fantabulous Emancipation of One Harley Quinn.
Fortnite is known for doing great crossover events in the past with Avengers: Infinity War, Avengers: Endgame, and most recently Star Wars: The Rise of Skywalker.
