IL2CPP Dumper for Arknights: Endfield & Unity Games

Simple injectable DLL that dumps IL2CPP metadata from Unity games (classes, fields, methods, namespaces, interfaces, etc.).

Originally created for Arknights: Endfield.

Features

• Dumps every assembly from GameAssembly.dll
• Two output formats:
  • Classic C# style - readable .cs files with proper syntax, access modifiers, inheritance & interfaces
  • AI-friendly - structured plain text, perfect for LLMs, code generation or parsing
• Activation: press INSERT after DLL injection
• Output paths:
  • Normal dumps -> C:\IL2CPP_Dump_Normal\
  • AI dumps -> C:\IL2CPP_Dump_AI\
• Log file -> C:\IL2CPPDump_Log.txt

Supported IL2CPP versions

IL2CPP metadata ≈27-29 (Unity 2021.3 - 2023.x - 2024.x builds)

Example outputs

Classic C# format (looks almost like real source code):

AI-friendly structured format (easy for AI tools):

Usage

1. Inject the DLL into the game process (any injector works)
2. Press INSERT while in-game
3. Wait for completion (watch the console and log file)

Great for reverse engineering, modding, cheat development or feeding game structure into AI models.
