AssetStudio is a tool written in C# that lets you open, browse, and extract the internal files from Unity game projects. Unity is a popular game engine that packages its graphics, audio, and other content into special container files called "assets" and "assetbundles." AssetStudio gives you a way to read those containers and pull out the individual pieces inside them. The tool supports Unity projects ranging from version 3.4 all the way up to 2022.1, which covers many years of games. Once you load a file or folder through its menu, you can export different types of content: images (Texture2D and Sprite files) can be saved as PNG, JPEG, BMP, or TGA; audio (AudioClip) can be saved as MP3, OGG, WAV, or M4A; 3D models (Mesh) export as OBJ files; and full 3D character rigs with animations (Animator) export as FBX files, a common format used in 3D software. Text data and shader files can also be extracted, as can video clips and fonts. For MonoBehaviour assets, which store custom game script data, AssetStudio will ask you to point it at the game's assembly folder (typically called "Managed") so it can read the data structure correctly. The README also mentions a companion tool called Il2CppDumper for games that use a specific low-level compilation method. To run the tool you need a version of .NET installed on your computer (.NET Framework 4.7.2.NET Desktop Runtime 5.0, or .NET Desktop Runtime 6.0 depending on which build you use). Building from source requires Visual Studio 2022. The README notes the project is not affiliated with or authorized by Unity Technologies.
