From their announcement:
After a long wait the latest version of Unbridled Fury, the universal fantasy miniatures skirmish game, is online and ready for download.
We are really happy with this latest incarnation of the game. We’ve spent a lot of time trying to iron out whatever inconsistencies it had and have made extra clarifications wherever we could. We consider this to be the best version of the core game yet available.
The beta will run for two months or so and expire when the rules are locked down and we begin to get into some new material for the game.
