Viewing post in Open-source Unity 3D Assets comments
I'm not affiliated with this game; they have probably imported these assets to their Unity project from Asset Store. These assets have been on Asset Store for a long time. You can find a description of each asset in the "Here is a list of my growing number of assets" section.
P.S. You can find the original release date of assets at the bottom of the Releases section in Asset Store.
