What kids of perks are there?
In Call of Duty 4 and World at War they add many perks. CoD4 features perks like “Dead Silence”, which makes it so that you walk quieter than normal, “Deep Impact”, which makes bullet penetration through walls even more damaging, “Overkill”, a perk that allows you to carry two primary weapons, and so much more. It’s just hard to list all of them.
