How to unlock the Head Hunter achievement in InFamous 2 - Definitive Guide
You won’t unlock the Precision power until later on in the story, by competing “Good Gets Better”. Once you’ve completed it, you can access Precision at anytime by pressing on the D-pad.
As described in the trophy, your goal is to do three successful headshots in rapid succession. By that, the “Amazing! 3-in-1 Blow” stunt bonus must show up on screen. Rather than attempt this during the story or a side mission, try to instead look for militants in groups of four patrolling the streets when you're not in a mission. Once you’ve found one, head to a nearby rooftop without gaining their attention, or engage them Rambo style at the risk of sustaining heavy damage, and take aim.
Place three well aimed headshots, and the trophy will unlock.
