In Call of Duty: Modern Warfare 2, it allows the player to gain their killstreak rewards with one less kill. For instance, if the player had UAV, Care Package and Predator Missile as killstreak rewards, rather than needing three, four and five kills respectively, they would only need two, three and four kills respectively.

Hardline Pro is unlocked after obtaining 40 killstreak rewards (not getting at least a two kill streak 40 times, as some may think). The easiest way to do this is set the player's killstreak to the rewards that require the lowest amount of kills possible. Hardline Pro reduces the number of deaths needed for a deathstreak by one.

The "Preemptive Strike" title is unlocked by completing Hardline Pro I Challenge. The "Close Support" title is unlocked by completing Hardline Pro VI Challenge along with the perk emblem.

Hardline returns as a Tier 1 perk in Call of Duty: Black Ops.

Overview

Hardline reduces all killstreak requirements by one. Its Pro version allows the player to re-roll the Care Package killstreak by double-tapping the action button for console versions and the reload key for PC versions, which will change its contents randomly. A Care Package can only be re-rolled once, and will always change its content.

Originally, the SAM Turret, Sentry Gun, and Valkyrie Rockets killstreaks crates could also be re-rolled; however, the December 14, 2010 patch limited Hardline Pro's functionality to the Care Package alone. One also cannot re-roll booby trapped Care Packages, making it easier to tell if one has been hacked.

Below is a table showing the default Care Package probabilities compared to the re-roll probabilities. As can be seen, re-rolling favors middle killstreaks much more than Care Packages, while higher killstreaks are almost unchanged.

Reward	Default %	Re-Roll %
Ammo	20%	9%
Spy Plane	15%	9%
Counter-Spy Plane	15%	9%
RC-XD	9%	9%
Valkyrie Rockets	5%	9%
Mortar Team	5%	9%
Sentry Gun	5%	9%
SAM Turret	5%	9%
Rolling Thunder	3%	4%
Grim Reaper	3%	4%
Napalm Strike	3%	4%
SR-71 Blackbird	3%	4%
Attack Helicopter	3%	4%
Death Machine	2%	3%
Chopper Gunner	2%	3%
Attack Dogs	1%	2%
Gunship	1%	1%

Hardline gives the player model medium body armor in the form of Kevlar vest, a helmet on some models and a radio device located on the character's shoulder. However, this particular device is only aesthetic; all players have a radio to call in Killstreaks.

Hardline returns as a Tier 2 perk in Call of Duty: Modern Warfare 3.

Overview

Hardline Pro is unlocked by obtaining 80 point streak rewards using Hardline.
