Ultra-popular battle royale Fortnite coming to iOS and Android soon with cross-platform support

And the best thing is, the game won't differ from its desktop/console counterparts.
“On phones and tablets, Fortnite is the same 100-player game you know from PlayStation 4, Xbox One, PC, and Mac,” Epic Games said in a blog post. “Same gameplay, same map, same content, same weekly updates.”
Best thing is, the mobile versions of the game will support cross-play and cross-progression between all platforms that the game will be eventually available on - PlayStation 4, PC, Mac, iOS, and Android. Fortnite players will be able to play against their pals no matter the platform, which is a double-edged sword - the pure universalism of the game and it's free-to-play aspect will likely cause its popularity to skyrocket even further, but will also fuel the "PC masterrace" narrative even more. And for a valid reason - humanity is yet to invent anything superior to the unbeatable, tried-and-proven keyboard/mouse combo.
Have in mind that the minimum hardware requirements for Fortnite mobile are iPhone 6S/SE, iPad Mini 4, iPad Pro, iPad Air 2, or iPad 2017 devices - anything older than that and you won't be able to play the game even if you receive the code.
