Even though Fortnite is all about the battle royale PvP these days, its world does change and develop, offering players tantalizing mysteries such as a falling comet and a missing Durr Burger mascot.
Players have wondered what happened to the burger sign following rifts that have been opening up all over the island. Now we know — it popped up in the very real Californian desert alongside a police car and a tent. This really weirded out the photographer who discovered it, as he was not a Fortnite player. Later visitors encountered an “Agent” character who handed out small notes that encouraged players to call a number.
This is all part of a new ARG for Fortnite, which players have been attempting to solve as a community. It looks like some sort of promotion for the newest season of the game. You can follow the developments on Reddit and on the Game Detectives wiki.
