Kill 5 enemies by dragging them behind a vehicle with the grappling hook.

Firstly you will need to know how to attach an enemy to a vehicle with the grappling hook. So, aim your crosshairs at an enemy then press & hold the button to attach the grappling hook to him. Next, turn towards the vehicle you are going to drive and aim the crosshairs right at the middle & let go of the button. The enemy should now be attached to the vehicle, so when you start driving you should drag him along with you. Just keep driving until you see Drag Kill come up at the top of your screen, this will signal that you killed the enemy successfully by dragging him.

I recommend you choose any car for this and not a motorcycle. I tried this with a bike but it takes too long for the enemy to die because it doesnt seem to drag him around as hard and do as much damage as a car.
