(adsbygoogle = window.adsbygoogle || []).push({}); In MY opinion I think the best perk in the game is Scavenger and the 2nd best is cold blooded.

Scavenger is the best because if you are good and stay alive for a long time, chances are that you will run out of ammo but not with scavenger pro you won't

Cold Blooded is great too because the enemy never knows where you are on the map unless they physically see you.

What is your favorite perk and why?

none, perks dont help me
