Last night was an interesting gaming session. What started as a simple game of kill teams rapidly evolved into 6 way 'every man for himself' kill team war.
For the most part it was normal kill team rules with each side fighting from a corner of table edge deployment arc. One interesting rule was introduced: At the start of the turn we had a 6 way roll off to decide turn order, meaning that it was quite possible to be the 6th person to go in turn one, then the first person to go in turn 2. This twist really helped open up the action and forced players to think much more about their moves. We also dispensed with the break-test rule meaning that each player fought until they were wiped out totally.
As the evening went on it became clear to the other 4 of us that this game was going to come down to a fight out between the 2 Orc players. The blood angels were the first to falter, with the Chaos marines following shortly after. My own Genestealer Cult (imperial Gaurd) force was the next to go in the same turn as the thousand sons player. The game boiled down to a wartrack, mec and burna all trying to overpower a solitary grot tank before it filled them with lead. They failed and in the last gasps of the 30-somthingth turn the grot tank tood alone and victorious.
Big scale kill teams... give them a try
