What are the cod mw 2 perks?

Answer 1

There are 15 perks in MW2. Each perk can be upgraded to a pro version. There are 5 in the 3 tiers:

Tier 1 - Blue:

Marathon: Unlimited Sprint / Marathon Pro: Climb Ladders and Objects Faster

Sleight of Hand: Faster Reloading / Sleight of Hand Pro: Aim down the sight faster

Scavenger: Resupply from dead enemies / Scavenger Pro: Extra ammo

Bling: Have 2 attachments on primary weapon / Bling Pro: 2 attachments on secondary

One Man Army: Switch classes in-game / One Man Army Pro: Switch classes faster

Tier 2 - Red:

Stopping Power: Increased bullet damage / Stopping Power Pro: Increased bullet damage towards aircraft

Lightweight: Increase speed by 7% / Lightweight Pro: Aim down sight faster after sprinting

Hardline: Killstreaks require one less kill / Hardline Pro: Deathstreaks require one less kill

Cold Blooded: Invisible to thermal scopes and enemy killstreaks / Cold Blooded Pro: When enemy aims at you no red name or red crosshair appears

Danger Close: Increased explosive damage / Danger Close Pro: Increased killstreak damage

Tier 3 - Yellow / Green*:

Commando: Increased melee range / Commando Pro: No fall damage

Steady Aim: Increased hip-fire accuracy / Steady Aim Pro: Hold breath longer with sniper rifles

Scrambler: Jam enemy radar (mini-map) when close to them / Scrambler Pro: Delays claymore explosions

Ninja: You do not appear on enemy heartbeat sensors / Ninja Pro: Silent footsteps

SitRep: Detect enemy equipment through walls / SitRep Pro: Enemy footsteps are louder

Last Stand: When killed you drop down and start to bleed out with a pistol / Last Stand Pro: Use equipment in Last Stand

Here are the levels at which you unlock the perks:

Level 1 - Marathon, Sleight of Hand, Stopping Power, Lightweight, Commando, Steady Aim

Level 9 - Hardline

Level 13 - Scavenger

Level 17 - Scrambler

Level 21 - Bling

Level 25 - Cold Blooded

Level 29 - Ninja

Level 33 - Danger Close

Level 37 - SitRep

Level 41 - Last Stand

Level 45 - One Man Army

After level 45 all perks are unlocked. You must be at least level 5 to unlock pro perks because level 5 is the level at which Challenges are unlocked and they are what are required to get Pro Perks.

* I say Green / Yellow because some perks in the Tier look yellow and one looks particularly green and there is much debate so I just say both.
