Now how about having some abilities on the character based on color/name of the human you get? Maybe having grey with a stealth ability that would stop all robots from moving once a round until you attack or shoot an arrow? Green throwing his sword like a boomerang? I also once got a character named bowman and man did i feel like i needed a special ability with the bow it would just make it feel hecka of alot more cool.
Abilities on the characters
This could also change how players play the game, some people stick to one path and this could force them to go for upgrades to go with the perk. I was thinking that you could get a separate mini perk for each area, color, name, and occupation then you could have a ability that you can use once per match that combines all the areas/perks.
