## What it is
Cpp2IL is a work-in-progress tool that reverses Unity's IL2CPP build process, recovering managed DLLs from IL2CPP-compiled games. It parses IL2CPP metadata via LibCpp2IL, analyzes platform-specific assembly into an intermediate instruction set, and regenerates CIL for inspection in tools like ILSpy.

## Use cases
- recover managed dlls from an il2cpp unity game
- decompile il2cpp game code to inspect method logic
- dump il2cpp metadata for modding a unity game
- analyze il2cpp binary structures programmatically via LibCpp2IL
- reverse engineer unity game internals
- view what a method does in an il2cpp build

## When to choose
- you need to inspect or recover code from an IL2CPP-compiled Unity game
- you want a library (LibCpp2IL) to parse IL2CPP metadata in your own tooling
- you're doing game modding or security research on Unity titles

## When to avoid
- you need polished, fully accurate decompilation - output CIL is messy and the rewrite is incomplete
- you're targeting non-Unity IL2CPP-like toolchains
- you need a stable API - the development branch is subject to change
