One of those will require you to run around the game world in search of Rift Portals to use, which is much easier said than done. Rifts played a key part in the lead up to Season 5, transforming large areas of Fortnite's island. Interacting with them teleports you high into the air above the island, allowing you to plummet down to the ground or use the elevation to glide around. > The difficult part of this challenge is actually finding these portals, as they appear randomly. Generally, you'll have to run around and just keep your eyes open, so we recommend just getting on with the other challenges and staying alert. However, there is one extra tell to look out for: when a rift opens, you'll hear a booming sound that serves as an audio cue to alert players nearby that one has opened, so keep your headphones on and turned up.
