The elusive Fortnite burger is a burger that it seems everybody wants but nobody knows how to obtain. See, the first step is to log on to any given Fortnite game and when you're on the battle bus ready to drop with your boys you gotta bust out a Big Mac and stick it into your CD slot on your computer. After you've done this it should accept the Big Mac and after a few business days it will eject your Fortnite burger.
