A new update is on the way for Fortnite. Epic has announced it is rolling out the 5.30 content update across all platforms--PS4, Xbox One, PC, Nintendo Switch, and mobile--tomorrow, August 28, and it looks like it'll introduce another new item to the battle royale game.

The update is scheduled to go live at 5 AM PT / 8 AM ET / 1 PM BST. Unlike most other updates Epic deploys for Fortnite, the developer says this one won't require any downtime, so you'll be able to continue playing Battle Royale without any interruptions.
