Batman: Arkham Knight

This achievement is tied to the 2nd Two-Face bank heist on Founder's Island.
As with the first one, I highly recommend to make use of the inital phase of this predator like mission. The goons won't focus on you because they are focusing on the heist itself. Take out as many as possible in this phase to make things easier for you in the second phase.
Also, like in the first heist I recommend to stick around the car of the goons after you have FEAR available. They will be very close together, which should make it easy for you to get a 5x fear combo kill.
