You can't call HoloLens 2 a gaming platform, but Microsoft is at least laying the groundwork. Epic Games has announced that it's adding HoloLens support to Unreal Engine 4, the technology that powers a wide range of games and 3D productivity apps. It's "up and running" now, Epic's Tim Sweeney said, and should be available to all developers in May. You're not about to play an augmented-reality version of Fortnite. It should allow for "photorealistic" 3D in AR apps, though, and it's really just the start of Epic's plans.
