Manipulator

Manipulator is an achievement/trophy in Dishonored. 
==How to Acquire==
In order to get this achievement, Corvo Attano must cause five enemies to accidentally kill an enemy of the same type (guards to kill guards, weepers to kill weepers, etc.).
A very easy way of achieving this in a high chaos playthrough is to enter the building to the right of the Boyle Estate main gates, in the mission Lady Boyle's Last Party.  At the bottom of the stairs, there are six weepers in close proximity to each other.  Run towards them until they are on high alert, then Bend Time, knock out five of them (leaving one conscious), and unfreeze time. The remaining weeper's area attack will kill the five unconscious weepers, and the achievement will unlock.
An even easier method can be executed during the mission House of Pleasure. In the Distillery District, knock out five thugs, and line them up on the barrels behind the small wall. Get behind a thug and attempt to knock him out. As he is hostile now, run to the barrels, and he will burn both Corvo and his allies.
Another easy method is to knock any guard unconscious and carry his body until being sighted by tallboys. When they shoot their incendiary bolts at Corvo they will kill their ally. However, this must be done multiple times to unlock the achievement, and the tallboys can do considerable damage to Corvo. Therefore, it's a good idea to accumulate five unconscious guards in an out of the way area near a tallboy before luring said tallboy back to deal the death blow on all five.
The enemies do not have to be killed at the same time, or on the same mission, as long as the deaths happen across the same save/playthrough. Enemies from different factions killing each other do not count as the game does not see them as allies. You can still mix and match cases of ally killing from any faction, for example, three cases of guards killing guards and two case of thugs killing thugs would unlock this achievement.
