Modern Warfare 2 Perks List

Infinity Ward has brought back the Perks system, with a few new twists. There are 3 perk slots as usual, but each perk has an additional level or "Pro ability." So, you may unlock and use a new perk, but there is yet another level of the perk.

For example, Sleight of Hand allows you to reload faster. However, the Pro Ability of Sleight of Hand allows you to reload faster and aim down the sight of your weapon faster as well.
