Fortnite’s Playground mode, a limited time event announced last month, is coming soon. The mode was listed in the new updates message over the weekend, accompanied by a brief description: “Let your creativity run wild on your own private island!” I’m always moaning about never being able to build anything cool in regular Battle Royale, so this sounds like just the ticket. 

A private island doesn’t have to be a lonely place, either. The original announcement from May mentioned that you could be joined by your squad.
