I don't believe there is a link up yet for the rules, however, the tendency is usually the same:
-2500 points of a current, legal ( not appendix or white dwarf list ) army
-no painting requirements
-no sportsmanship scores, no painting scores, no composition scores
Thats about it. To sum the 'Ard Boyz tournaments up: Make the most abusive, blatantly exploitative, win at all costs army you can think of. Don't expect to make friends, especially with prizes for top finishers, any degree of sincerity and mercy is gone. Welcome to the tournament environment created by Games Workshop.
