The ROG Xbox Ally is a PC gaming handheld manufactured by Asus, and the latest iteration of its ROG Ally range. Its Xbox branding reflects the deal between the two companies that has made the Ally the launch pad for Microsoft’s new “Xbox full screen experience”: a streamlined, console-like front-end for gaming on the Windows operating system. Think of this as Microsoft’s version of Steam’s Big Picture Mode, which is the default interface for the Steam Deck.
