pit fighter rules

[davve]

Hi,
everywhere I go I read about pit fighter rules with 'styles'. For example lists where people say: I have a warrior armed 'chaos style' and two guys 'undead style' and so on. I downloaded the rules on the specialist website (right here: http://www.specialist-games.com/assets/PitFighterWarband.pdf) but I see nothing on these styles??
Can anybody help me out please?
Thx

Perhaps its just nicknames on how theyr armed?

The models have chaos, undead lizardman style armour & weapons I think thats what was meant.
