Fortnite for iOS is officially available for everyone. Invites are no longer necessary. That means you get Fortnite! And you get Fortnite! Android users, you get bees. Fortnite is coming to Android soon though, don't worry.
Epic Games snipped the ribbon on Fortnite for iOS this morning. It's a free download; all you need to play is a compatible device, which include the iPhone SE, 6S, 7, 8, or X, as well as the iPad Mini 4, Air 2, 2017, or Pro.
No invite needed - Fortnite is now open everywhere on iOS. Grab your friends and jump in now! http://go.redirectingat.com?id=87431X1573192&xs=1&url=https%3A%2F%2Ft.co%2FqU3S8QAQ9K— Fortnite (@FortniteGame) April 2, 2018
Incompatible devices include the iPhone 5S, 6, and 6 Plus, as well as the iPad Air, Mini 2, Mini 3, and iPod Touch. As for Android, Epic's official site for Fortnite Mobile states "Android support is coming within the next few months. If you are on an Android device, please click 'Get Started' to sign up. We’ll notify you when your Android device is supported."
Hopefully Epic is prepared for the inevitable influx of traffic: Fortnite Mobile had no problem racking up a huge player base even when the game was invite-only.
