Great Book for Project-Based Learning
Format: Paperback
As a Unity Instructor I can say the book is really amazing I was expecting that I'd face a basic book, but instead, the book is very complete, even having AR and VR chapters totally adapted to the new version of Unity, which makes it one of the best books to master Unity (if not the best).
