I've checked through my mission stats for every mission; I've killed zero hostiles and zero civilians on every level (a couple of unconscious bodies found in each level), and I didn't get the 'Clean Hands' achievement.
I avoided swordplay and shooting just for the achievement, and I didn't even get the damn thing?
Did you get the ghost or shadow achievement? If you did that means you either killed a key target by mistake or killed the assassin's in the prologue (which i dont think counts against you but people are debating that)
There's different kinds of caring. I care enough to be an *** but I don't care enough to consider his opinion valid to influence anyone's opinion - diablo2lod12
