Here is the full list of perks and perk challenges for Call of Duty: Black Ops for the PS3, Xbox 360, Wii, and PC. Each tier can only have one active perk at a time, so you can have three active perks at once. Each perk costs the same to unlock at 2,000 credits, and each Pro Perk upgrade costs the same as well at 3,000 credits.

It’s important to remember that you MUST purchase the pro perk after it is unlocked in order to use it. I see a lot of people on forums and boards saying that a pro perk doesn’t work after it’s unlocked, but they simply forgot to purchase the upgrade.

Each primary perk is listed in red, with the pro perks and pro perk challenges below them. I have also included links to the specific pages I have created with tips to help you complete the pro perk challenges for those perks.
