In other words, **Ugly as Sin v4.5.0** targets **Hideous Destructor v4.5.0** which targets **GZDoom 4.5.0**. Will sometimes include a **Stable Legacy** build for LZDoom compatibility when needed and possible.
 * [**Unstable**](https://github.com/caligari87/Ugly-as-Sin/archive/master.zip) - Also sometimes called the `master` build. Constantly-updated version which targets the latest `main` development version of Hideous Destructor. Most up to date but may have bugs, testing features, or be broken.
-* [**Unstable Legacy**](https://github.com/caligari87/Ugly-as-Sin/archive/refs/heads/legacy.zip) - The same as the **Unstable** build but targets LZDoom compatibilty when possible. May be missing features.
