Hellmaker

Hellmaker is user-friendly, full-featured level editor for the Apple Macintosh. It was created by Paul Davidson of Australia.

The current stable version is 1.1. Version 1.2b2 features a 3D preview and supports Hexen WADs, but it is buggy at times. WADs can still be built exclusively with that version, however.

The homepage for Hellmaker is no longer available, but both versions can be downloaded at the website below.
