This is a bit difficult to explain.
I was playing Thief 3(I know it's not actually called "Thief 3", but I'm still gonna call it as what it's suppose to be. Shut up.), and I noticed how sensitive each Guild fells about dead/unconscious bodies lying around, attacking anyone who gets near.
So I knocked out few random civilians, threw them in the streets and waited for some random Hammerite or Pagan to pass by. Then they would begin to search for the suspect, and kill him. Which would then gather the attentions of the City Watch, who'll start attack the Pagans/Hammerites, who will in turn strike back. Then the other Guilds join the battle, so it goes to full circle, with everyone killing everybody constantly.
Thus; Perfect chaos. And I love every second of it.
Also, from the same game, I would throw bodies to elevator shafts.
