New York: Microsoft came to the defence of the maker of video game sensation Fortnite on Sunday, saying in a court filing that Apple's moves to cut off the company from programming tools would hurt other game creators and players as well.
Epic Games is locked in a legal battle with Apple after trying to dodge commission payments due to the tech giant, prompting the iPhone maker to pull Fortnite from its online store.
Apple also threatened to cut off Epic's access to its programming tools needed to maintain "Unreal Engine", a software platform that was developed by Epic and which is used by many video game studios to create graphics.
In a filing to the California court handling the case between Epic and Apple, a Microsoft manager said Unreal Engine "is critical technology for numerous game creators including Microsoft".
"Apple's discontinuation of Epic's ability to develop and support Unreal Engine for iOS or macOS will harm game creators and gamers," wrote Kevin Gammill, Microsoft's general manager of gaming developer experiences.
Apple has alleged that the Fortnite maker deserves to lose its access to the programming tools because it violated the terms of their contract.
At the heart of the fight is the 30 per cent that Apple takes on the revenue generated by companies to distribute their apps through its online store.
Epic Games filed a lawsuit against Apple last week after the tech giant took Fortnite off its App Store for releasing an update that dodges revenue sharing.
The latest version contains a payment system that lets player transactions bypass the App Store, preventing Cupertino-based Apple from collecting its typical 30 percent cut.
Epic has asked a judge to make Apple put Fortnite back in the App Store until the matter is resolved in court.
