I shot the grappling hook out at the ledge of a building, using it to pull myself towards it at an angle so that I could use it to swing it around a corner.
As soon as I swung around the corner, I found my targets under me, which happened to be two guys currently fighting in close quarters with their knives after they ran out of bullets trying to kill each other.
They looked up to see me swinging towards them with one hand holding on to my grapple and my other hand pointing my rifle down towards them.
I squeezed the trigger and rained down fire on them, quickly killing one while the other managed to dive out of the way as his shield saved him from being eliminated. For now, that is.
I detached my grappling hook and dropped down towards the ground, spinning myself around in midair to level my gun at him once more.
I fired another shot that broke his shield before finishing him off with two shots to the head.
