Unbridled Fury is a modular rules system; it has a core rulebook which is essential to play the game, and a whole slew of supplements and lists that extend the game in all kinds of directions.
The downloads on this page are the core files that you will need to play the game, along with a host of other files which you may find helpful.
The core rules are available in two forms: a full colour PDF rulebook (for viewing on-screen) and a black-and-white low detail version (for printing at home). In the future we have plans for print on demand (PoD) and even eBook versions of the core rules.
