Chapter 12 - Gibraltar Bridge
"Can I play, daddy?" difficulty.
5 kills within 10 seconds using a detached turret gun.
This is early on in the chapter. Keep going until you get to a train that will have enemies that start shooting at you before you even look out the train car.
There will be a robot that has a turret (the one I am using) and a few enemies in a train car. Also, there will be a turret that activates if you go on top of the train car.
