loading project instead of scene for robot tutorial

For some reason, when I downloaded the 3d platform tutorial, there was no clear way for me to run the actual project. I tried File->Open Project but it wouldn’t let me click anything. All I can do is Open a scene, and Unity says I am missing a lot of assets when I do.

File->Open Project usually lets you navigate to the folder where the Assets folder is found and you can open that (parent) folder.
