Betrayal at Badab: A Betrayal at Calth Rules Mod

Hello, and welcome to the home blog post of the Betrayal at Badab project. This blog post will contain links to all of the files I have created to allow players to use the Horus Heresy: Betrayal at Calth rules specially modified for the Badab War.

This project was launched because I have always been interested in the Badab War from the first time it appeared in White Dwarf issue 101 back in 1988. I enjoyed the lore of a civil war between Space Marine chapters. As someone who loved the Warhammer 40,000 universe, but did not like the rules, I was looking for a way to play the Badab War without actually using the rules. When Games Workshop released the boxed game Horus Heresy: Betrayal at Calth, I had found the system I was looking for.

Here you will find files for playing the Badab War using the Horus Heresy: Betrayal at Calth rules. They are written by me and edited by Steve Bledsoe, who has done a great job helping me clean them up and offer suggestions.

NOTE: These files do NOT contain the rules for Horus Heresy: Betrayal at Calth. You will need a copy of the boxed game and the dice to play. These files only contain the necessary information to use forces and characters from the Badab War for Horus Heresy: Betrayal at Calth.

Click the links below to download a copy of these free files.

Update: Space Marine Specialists added, such as Librarians, Chaplains, Techmarines, a Strike Force Leader (for those who don't want to take a major Company level character), and an Apothecary.

The files include (or will later include) the following:

Command Cards for Loyalist and Secessionist forces
Weapons List
Tabletop Rules Conversion
Space Marine Specialists

Unit Cards and special characters for:
Astral Claws
Fire Hawks
Howling Griffons
Mantis Warriors
Marines Errant
Red Scorpions
Sons of Medusa


  1. Great stuff! Thanks for posting it.

  2. No problem! Hope you enjoy and find them useful. I'm hoping to get the Carcharodons up next. Let me know if you have any questions!

  3. Played this recently and had so much fun! Great work :)
