These are the perks you can use in the Black Ops multiplayer mode. As with previous titles, there are 3 different slots (blue, orange and green). All perks are unlocked at level 4 and they can then be purchased with COD Points (cP). The first perk slot will determine the appearance of character, so if you equip the Ghost perk then your character will wear a ghillie suit.

To unlock the PRO+ version of a chosen perk, you will need to complete 3 different challenges specific to that perk. To view those challenges, click on the "Challenges ↓" link.
