Microsoft filed a brief in support of Epic Games and says Apple is in the way of it offering a full Xbox storefront on iOS.

In addition to the handheld, Microsoft has also been trying to launch its Xbox Mobile store, but it has reportedly been delayed because of Apple.

Microsoft says Apple's App Store rules are to blame for the continued delay of the Xbox mobile app store it announced last summer. In an amicus brief filed this week first spotted by The Verge, Microsoft expressed support for Epic Games in the company's long-running bout against Apple.

New details about the next gen Xbox console suggest it will focus on support for Steam and Epic Games Store, potentially bringing Sony first party titles to Xbox.

These environments will need Steam integration, @eXtas1stv believes, and Steam will be available in the Microsoft Store in these upcoming devices. The Epic Games Store could also make an appearance in the Microsoft Store, according to @eXtas1stv’s video.
