You can do this on Chapter 12 - Checkpoint 11, right after you blow up the foundation of the building and the roof starts to collapse. Easy way to do this is go near the enemy, wait for the tremor, and use bullet time to shoot him in the head. Tremor happens every 14 secs.
"The easiest way to do this is use the shotgun up close on a guy. Only one pellet needs to hit their head".- VooDeeZy
"This also unlocks when you are in last stand and get your 'revive-kill' as a headshot" - ZombieMaze
