How to Extract Assets from a Unity Game

Once you have downloaded and extracted the necessary files, it's time to begin extracting assets from your Unity game. This tutorial will guide you through the process of using ILSpy and AssetStudio to decompile a Unity game on Windows.

The first step is to download ILSpy, a popular .NET decompiler. You can do this by heading over to the releases page and clicking on the 'Assets' button at the bottom of the changelog for the latest release. Once you've downloaded the zip file, extract it to a folder where you'll be working on your project.

Next, install the .NET 6 SDK if you haven't already done so. You can do this by downloading and installing the latest version from the official website. Make sure to choose the installer that matches your CPU's architecture.

Once you've installed the .NET 6 SDK, open a Command Prompt and enter the command `dotnet -list-sdks` to verify that it's installed correctly. If you don't see a 6.X.X entry in the list, or if you get an 'dotnet is not recognized' error, you'll need to reinstall the SDK.

With ILSpy installed and verified, you're ready to start extracting assets from your Unity game. In this tutorial, we'll be using the sample game 'Avoiding Responsibility' to demonstrate the process.

To begin, download the sample game by clicking on the 'Download Materials' button at the top or bottom of this page. Once you've downloaded the zip file, extract it to a folder where you can access its contents.

Using ILSpy and AssetStudio to Extract Assets

ILSpy is a powerful tool that allows you to decompile .NET assemblies and view their source code. In this tutorial, we'll be using it to extract audio and 3D models from the sample game.

To get started with ILSpy, simply open the program and select the assembly you want to decompile. You can do this by clicking on the 'File' menu and selecting 'Open' or by dragging and dropping the assembly file into the ILSpy window.

Once you've opened the assembly, you can use the various tools in ILSpy to navigate its contents and extract specific assets. For example, you can use the 'References' tab to view a list of references used by the assembly, or the 'Types' tab to view a list of types defined within it.

AssetStudio is another powerful tool that allows you to extract assets from Unity games. It's designed specifically for extracting audio and 3D models, making it a great choice for this tutorial.

To get started with AssetStudio, simply open the program and select the game you want to extract assets from. You can do this by clicking on the 'File' menu and selecting 'Open' or by dragging and dropping the game file into the AssetStudio window.

Once you've opened the game, you can use the various tools in AssetStudio to navigate its contents and extract specific assets. For example, you can use the 'Audio' tab to view a list of audio files used by the game, or the '3D Models' tab to view a list of 3D models used by the game.

In this tutorial, we've learned how to extract assets from a Unity game using ILSpy and AssetStudio. We've covered the process of downloading and installing ILSpy and AssetStudio, as well as how to use them to decompile assemblies and extract audio and 3D models.

Remember that stealing code and assets and claiming them as your own is illegal and unethical. This tutorial is intended for legal use cases like recovering projects you made yourself or for educational use. With great power comes great responsibility!
