Meh they will just slow down Fortnite or make it eat battery. There's million ways Apple can turn people away from it. No problem though, Fortnite is crap anyway.
Epic Games first launched Fortnite for iPhone in 2018, but Apple removed the game from the App Store in 2020 after the title received a new payment method for in-game items. After four years, the game made its return on iOS, but it's only available in the EU.
