The Batman / Fortnite Crossover Sees The Dark Knight Thrown For A (Time) Loop Have you seen Memento? If not, you should rectify that sharpish; it's one of Christopher Nolan's best and comes from a time before you needed three viewings to get a handle on his movies. In it, Guy Pierce's Leonard is trying to solve a grisly mystery — a task made considerably more difficult by the fact his short-term memory resets every few hours and he forgets everything that's happened since a traumatic accident which caused his condition. Yes, yes, but what's that got to do with this Batman / Fortnite thing, you ask? Well, in this new crossover comic book series it seems that ol' Bats finds himself dropped on Fortnite Island with severe memory loss and stuck in a 22-minute time loop. Much like Leonard, the World's Greatest Detective takes to scrawling notes on his person to try and make sense of the mystery — all while doing battle (royale) in a fight for survival, of course. Take a look at the launch trailer above for a better idea.
