I got this book called "Learning C# by Developing games in Unity5.x" by Greg Lukosek and I'm stuck on chapter 9 where he asks to download the Player.unitypackage file. I cannot find it nor can I find any answer on the net, help please

Chapter 9 Page 120
Preparing the player prefab

I found the link he set up

He says you have to sign in or something, found it on this forum post after looking the book up :

https://forum.unity3d.com/threads/learning-c-by-developing-games-with-unity-5-x-s-ebook-available-for-free-today-29th-march-2017.463413/

This link worked for me:
https://codeload.github.com/PacktPublishing/Unity-5-Learning-CSharp-by-Developing-Games/zip/master

The link from the best answer didn’t work for me ( packtpub gives me error for my registration and netiher can I contact them to their email).
