Use the launch pads at Guardian Towers to complete this challenge. The latest set of Fortnite challenges has arrived, and one of the new weekly challenges requires you to use the launcher from Guardian Towers. Guardian Towers are the mysterious spires that have popped up surrounding the actual Spire in the center of the map, and they have launch pads that can send you flying at the top of them. These launch pads already get a lot of use from Fortnite players, but this new challenge is sure to make these locations much more packed than normal. Here’s how to use the launcher from Guardian Towers in Fortnite.
