>>388 1st. Commando is the ultimate trash cleaning Perk. He has weapons with huge magazines, can neutralize targets afar and has really good grenades. As a Commando your primary purpose is to prevent Zeds even closing in on you and taking out priority targets before they have a chance to close the gap.
違うな こっちか While good at clearing trash, Commando is also really weak against Scrakes and Fleshpounds. They have a lot of health and are really resistant to small arms fire. On harder difficulties you might as well be shooting peas at them. Your real strength against them lies in your grenades.
