Don't get Dishonored (you will know if you do this obviously because the game will end)
Before the end of the fourth fight run from your opponent through the complex and find the manhole your character jumps down during the cut scene after the fourth fight.
Don't get hit once!! You cannot take a single hit. It's ok to let them hit your weapon but if you take ANY damage even from a sub weapon you can't get the special ending....
