Face Your Foe is a takedown gear perk that lets you perform takedowns on alerted enemies from the front. It keeps Machete Kills available even after a fight breaks out.
When soldiers are already hunting you, you can still run up and take one down from the front. That gives you a quick silent kill in the middle of a loud fight.
Very good for melee-focused players. It pairs well with machete play and close-range builds.
Disrespect and Pin Puller give your Machete Kills extra effects, so you get more out of each takedown.
