How to play game from just Assets and Project Settings?

I downloaded a zip of what is supposed to be a Hogwarts map. It came with he assets, projects settings, screenshots, a gitignore, and a README.md. How can I play it? There is no Unity file in it and no exe. I tried loading the assets and settings into a project but it came up blank.

That sounds like you’ve downloaded project files. In order to play the game, you would have to open that project in the Unity Editor and preview or build it from there. This assumes that the project’s current state is ready to be built. It probably is, but you never know.

The basic version of the editor is free from unity3d.com, so that’s a big undertaking but not impossible.

You might check that README.md file to see if it has any further instructions.

It’s also possible that whoever made this project could provide a build.
