Well, basically hardline pro is one of Tier 1's perks and it is unlocked when
In general getting 7 killstreaks in one match is fairly easy. you can die after every two to get 7 RC cars or uav's or if you want a challenge you can get all 3 of your chosen killstreaks about 2 times and then get a 2-kill streak to top it off.
with hardline pro it will give you double any equipement like semtex,tomahawk and flash bangs (does not give extra willy pete) this awnser is incorrect hardline pro lets you change the contents of a care package its warlord pro that gives you double NO THIS IS NOT TRUE HARDLINE PRO GIVES YOU THE ABILITY TO CHANGE WHATS IN YOURE CARE PACKAGE WARLORD PRO IS WHAT DOUBLES YOURE EQUIPMENT
Hardline pro also allows you to have to get one less kill to get killstreaks. (RC-XD=2 kills rather than three.)
makes it so it takes one less kill to get to your killstreak and if you have hardline pro it makes it one less death to get to your deathstreak. dumb perk though, i dont use it
Takes one less death for deathstreaks. etc finalstand, copycat
it makes kill streaks 2 kills less
This allows you to change a care package once per package.
You get to change your care package. For example if you get amo, you can change it to a spy plane
If you mean like a care package then it requires Hardline Pro.
Highlight the perk, press square (or whatever button for your console) and read about the challenges required.
get hardline pro get a care package double tap square or X to change it
you cant force car packages to be better but you can use hardline pro to ''reroll'' the package, changing its contents
Set your kill streaks to care package then get 5 kills (4, if you are using Hardline) then hopefully you will get a death machine. If you got Hardline Pro you got two attempts to get it. I got 3 death machines in one combat training match while using Hardline Pro.
You cant. When you get kills, that will add to your kill streak. Unless you have hardline pro (black ops), Which decreases the number by one.
To get the rc-car in black ops wii you have to get a three kill streak. if you have hardline you can get it in two kills.
It is a Perk used to gain a killstreak with one less kill. Very use full if you choke under pressure to get your killstreak. Hardline Pro gives access to change the care package drop to another random thing.
if you do hardline perk you can change care packages.
