If you are a game developer, you probably do not need an introduction to Unity. Basically, it is a cross-platform game engine that allows you to develop games for more than 25 platforms such as iOS, Android, Windows, Mac, Linux, etc.
If you are still reading this article, chances are that you are interested in getting to know more about these open-source repositories that can help you develop games using Unity.
A relatively new GitHub repository has already listed more than 800 open-source GitHub repositories organized in different categories that you can use and find as helpful for you.
It includes repositories for categories such as Shader, Editor Extensions, UI, Script, Mobile and a category named Other with projects that are not categorized in any of these categories.
You can find this list and even contribute with your open suggestions in case you have something in mind that may be relevant but that is not included in there yet.
I hope you find this helpful.
