A mobile version of Fortnite's battle royale mode is coming to iOS and the Android, Epic Games has announced.

According to Epic, Fortnite on mobile is the same 100-player game you know from PlayStation 4, Xbox One, PC, and Mac: "same gameplay, same map, same content, same weekly updates."

Hilariously, Sony has allowed cross play and cross progression between PlayStation 4, PC, Mac, iOS and eventually Android... but not Xbox One.

"We believe this is the future of games," said Epic.

"The same game on all platforms. Console quality graphics and action. Play when you want, where you want."

Players will be invited to the in-development build of of the game's iOS version as early as Monday.

Fortnite is currently the most-viewed game on Twitch and YouTube by a fairly wide margin.
