An experimental command-line toolset for Unity asset and asset bundle files written in Java, mostly designed for extraction.

The latest build can be found on the releases page.

0.3 works best with Unity 3.x and has most of the original extraction features.

0.4 is a somewhat incomplete and untested upgrade to support Unity 4 and 5 and has some of the extraction features of 0.3.

0.5 is a code rewrite to properly support all Unity games from 2 to 5 that also comes with unit tests. Right now, it only supports raw file reading and writing without any object deserialization, therefore it also can't extract any asset data directly.

disunity <command> [options] <file>

Note: depending on the platform, you may need to run disunity.bat (Windows) or disunity.sh (Linux/MacOS). In case the launch script fails, try java -jar disunity.jar.
