You've probably seen the music video for Childish Gambino's This is America doing the rounds, or at least some screenshots of it. Fortnite players certainly have, and a particularly creative bunch at YouTube channel WiziBlimp have got together to recreate it in Epic's Battle Royale shooter using the replay system.
Given the constraints they're working with, they've done a remarkable job. I played the two videos side-by-side at the same time, and they've nailed the camera swivels and pans from the original. Their characters all dance at exactly the right times, too. I especially like it when their emotes sync perfectly—just look at the timing of those backflips at 1:33.
It's not the only excellent clip that Fortnite's replay system has produced: James collected a few gems in a post last month.
