reversing-unity-il2cpp
Reverse engineer Unity games and apps built with IL2CPP or Mono, using Il2CppDumper, Il2CppInspector, and dnSpy. Use when an APK or IPA contains global-metadata.dat, libil2cpp.so, UnityFramework, or Assembly-CSharp.dll, when jadx shows only UnityPlayerActivity, or when the target is described as a Unity build.

# Reversing Unity IL2CPP
Unity ships in two very different shapes, and identifying which one you have
is the entire first decision. A Mono build hands you decompilable .NET
assemblies. An IL2CPP build compiles C# to C++ to native code, and the C#
metadata lives in a separate file that you must recombine with the binary
before anything is readable.
## When to Use
- The APK contains `assets/bin/Data/Managed/Metadata/global-metadata.dat` and
`lib/arm64-v8a/libil2cpp.so`
- The APK contains `assets/bin/Data/Managed/Assembly-CSharp.dll` (Mono build)
- The IPA contains `Frameworks/UnityFramework.framework`
