Perks in Call of Duty Modern Warfare 2: Slot 3
The slot three perks have a myriad of uses, from jamming enemy radar to giving the player a chance to cheat death, at least temporarily.
Commando is unlocked at level 4 and significantly increases the damage at which the player can kill an enemy with a melee attack. The upgraded version, Commando Pro, is unlocked after scoring 20 melee kills using Commando and allows the player to fall without taking damage.
Steady Aim is also unlocked at level 4. It increases hip-fire (shooting without aiming down the sight) accuracy with all weapons. The upgraded version, Steady Aim Pro, is unlocked after earning a total of 80 hip-fire kills using Steady Aim. Steady Aim Pro allows the player to hold their breath longer when using a sniper rifle.
The third slot three perk, Scrambler, is unlocked at level 17 and automatically jams the radar of enemies near your position, rendering you undetectable. After scoring 50 close-range kills using Scrambler, Scrambler Pro is unlocked, allowing you to delay the explosion of enemy claymores, hopefully giving you a chance to escape the blast.
At level 29, the Ninja perk is unlocked. Using this perk, players are invisible to enemy heartbeat sensors. The upgraded version, Ninja Pro, is unlocked after scoring 50 close-range kills with Ninja. Ninja Pro silences your footsteps in addition to your heartbeat.
SitRep is unlocked at level 37. SitRep allows you to see enemy explosive devices and Tactical Insertion flares much more easily. After you've used SitRep to destroy 120 enemy devices, SitRep Pro is unlocked, increasing the volume of enemy footsteps.
At level 41, one of the most useful (or annoying, depending of which side of it you are on) perks, Last Stand is unlocked. Fans of the original Modern Warfare remember that this perk allows you to survive an additional ten seconds after being downed by an enemy. During your Last Stand, you have use of your sidearm and can attack any nearby enemies. New to Modern Warfare 2 is the ability to crawl while in Last Stand. After scoring 20 kills while in Last Stand, Last Stand Pro is unlocked, allowing you the use of your equipment (claymores, grenades, throwing knives, etc...) after being downed.
Thanks to the various useful perks, weapons, and equipment loadouts available in Modern Warfare 2, players can create a class to suit their own personal playing style. Don't be afraid to check out the various perks to find the combination that works best for you.
