Rumbleslam Referees Expansion
Each of the new Referee models will come with their own rules. I mean...just imagine how creepy Death is going to be! You will also find rules for pinning and tripping included amongst other things with their release so watch this space.
One imagines that you can, in typical fashion, bribe that Goblin and the Werewolf is going to get stuck into more of the fights than the combatants!
