How to unlock the State-of-the-Art. Bang, Bang! achievement in F.E.A.R. 3 - Definitive Guide
This can be done in Interval 2, 4, 5, 7, Contractions or Soul King. Once you get a sniper rifle you need to kill 10 enemies in a row with nothing but head shots. This is easier if you're playing the Campaign with Pointman, use his slow motion to line up your shots. If you miss a shot it'll be fine, however if you shoot and or kill an enemy with a body shot, the counter will reset.
