You know your brand is huge when it gets its own day in a year. For Star Wars, that's May the Fourth. For Batman, that usually on the third Sunday of September or September 15. This year's Batman Day is, however, very special because it celebrates the 80th anniversary of the Caped Crusader, a.k.a. the Dark Knight. Knowing that many of its gamers may also be comics lovers, Fortnite is getting into the spirit with new Batman-related skins and weapons and, of course, a new map that looks like home for the billionaire crime fighter in dark tights.
