Hellmaker

Hellmaker is an easy to use, and full featured WAD editor for Macintosh. 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. You can still build WADs exclusively with that version though.

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