## What it is
A formerly popular repository hosting decompiled C# source code of Unity's engine and editor, which was removed at the request of Unity's legal team. Unity has since published an official C# reference source repository, making this project obsolete.

## Use cases
- read Unity engine C# source code for reference
- understand how Unity editor internals work
- find replacements for undocumented Unity APIs
- learn how UnityEditor.dll is implemented
- decompile Unity assemblies with ILSpy or dotPeek

## When to choose
- you need Unity's C# source code - use the official UnityCsReference repo instead
- you want to study how Unity internals are implemented

## When to avoid
- you want the actual decompiled code - this repo no longer contains it
- you need a maintained or licensed resource
- you are looking for an active tool rather than a historical reference

## Facets
- artifact type: learning-resource
- maturity: abandoned
- function: reverse-engineering, developer-tools
- domain: developer-tools, tutorials
- platform: cross-platform
- tags: unity, decompiled-source, c-sharp, removed-repo, reference-source, game-development
