How do you unlock hard line pro on black ops?

Answer 1

You must do these 3 things with Hardline equipped;

1. Share 10 care packages - This can be done with any form of care package not

just the 5 kill streak. This means that Sentry Guns and SAM turrets also count towards this.

2. Earn a 7 Killstreak in a match - Simple enough, kill 7 enemies without dying.

3. Earn 7 different killstreaks in a match - Not to be confused with the above, basically you need to earn (Not use, just obtain) 7 different killstreaks in one match. Easy way to do this is equip a Spy plane, Counter-Spy plane and Care Package.

Hardline Pro is the ability to change a carepackage once - ANY carepackage weither it's yours, a team-mates or an enemies.

Keep in mind that SAM turret package and Sentry Gun package can also be changed (3 kill streak for SAM turret with Hardline active) which means you could get a gunship for a 3 kill streak!

Hope this helps.
