How can I activate AR in the game?

If your device supports AR for the game, you should be able to see a button with the Apple AR logo at the top of the screen. Tapping this will give you the option to choose between God mode and Mortal mode. 

 

When viewing the game in God mode, on-screen instructions will help you to set-up the view on a surface correctly.

If you want to leave AR mode, simply tap the  “X” in the top right-hand corner and you will return to the standard in-game view.
