Following a round of server maintenance, a new update is now available for Fortnite. Patch 5.30 has arrived on all platforms--PC, PS4, Xbox One, Nintendo Switch, and mobile--and it introduces new items to both Battle Royale and Save the World modes, along with an assortment of bug fixes and other improvements.

On the Battle Royale side, Epic has introduced the previously teased Rift-to-Go. As its name suggests, this Epic rarity item is a portable rift that you can use to warp into the air and skydive back down. The rifts will last for 10 seconds once they've been activated, so other players will also have a brief window of time to jump into them.
