Malifaux Tournaments
We're hosting 4 Malifaux tournaments during the convention, so if you're looking for a chance to cheat fate, join us. We'll be giving prizes for 1st place, 2nd place, 3rd place, and best painted Crew. Please note that you must provide a painted Crew (except for miniatures released at Gen Con 2010 which must only be assembled, primered not required), and we'll supply the game boards. No proxies allowed. Strategies will be given for each round.
