Fortnite has gone offline worldwide on iOS devices after Apple blocked the online video game’s release submission. The video game’s social media pages put out the following statement: “Apple has blocked our Fortnite submission so we cannot release to the US App Store or to the Epic Games Store for iOS in the European Union.

Epic’s long-running battle with Apple over the future of Fortnite on iOS devices has taken another turn, with Epic accusing Apple of blocking its Fortnite submission so it can’t release the game to the U.

Epic Games has been waiting for Apple to approve Fortnite for the US iOS App Store for nearly a week, and now Epic CEO Tim Sweeney is using X to try and put pressure on Apple. On Thursday, he highlighted examples of Fortnite lookalikes that are currently on the App Store and made a direct appeal to Apple CEO Tim Cook.
