Mantic Games have made a beta version of their Kings of War fantasy rules available as part of a closed beta test.
From their website:
Just to let you know, our brand-new Kings of War rules will become available to download today a 6pm.
This is a closed public beta. To access our rules, you need to receive our newsletter – so if you or your friends want to participate, make sure you sign up to the newsletter now (those of you already signed up are already eligible for the beta).
Remember we want your feedback on the rules: we want to know what you like, what you don’t like, and what you maybe think we can add. We are going to be reading all of your feedback that you submit on our forum, as we have created a unique section specifically for you to talk to us about the game. So please submit your comments and suggestions.
