I played the game in AR before, on the Magic Leap. It's also available in VR. The iOS game, Angry Birds AR: Isle of Pigs, is the first mobile version with AR. After getting to play it for a moment, it's a reminder that, in many cases, phone-based AR can be just as good as what you can get on a several thousand-dollar AR headset.

Just like you'd imagine, the game involves slingshot-launching birds into blocks and making pigs blow up. The game's graphics are on a par with other ARKit-enabled games on the App Store, with some nice-looking physics and environmental effects like snow.
