well i have gotten every streak in the game from them lol.
vsat coming up alot.
Also if you run CP , make sure you unlock every scorestreak with a token.
any streak you get from a CP and you also have it unlocked in your scorestreak will count towards the challenges from that scorestreak.
so even those who cant get those high end streaks could do the challenges if they get lucky with a CP
Always unlock them as soon as they become available, the same with other equipment, using the blackhat means i dont have to carry betties or claymores to because i am picking up bonus kills by hacking them, i always enjoy getting those kills from an enemy players hacked betty or claymore..
hahaha yeah that is also pretty handy.
i started using the TI insertion to.
you can control respwans on HQ and an easy way to get revenge medals lol.
I got the calling card for shooting down enemy aircraft and have never used a launcher...all blackhats, and on my way to the betty and claymore one now to....
