Best Perks to Equip

Best Base Perks

Perk Name	Description
Overkill	Carry two Primary Weapons.
Scavenger	Resupply ammo and throwing knives from dead players.

Overkill makes you powerful in firefights since you'll be swapping to another primary instead of a pistol when you run out of ammo. This means you'll be outgunning enemies most of the time, and lets you create a loadout that can be effective at all distances.

Due to the fast-paced nature of MW2, you'll constantly be scrounging for ammo. Scavenger ensures you won't need to worry about being on your last mag during a gunfight.

Best Bonus Perks

Perk Name	Description
Focus	Reduce flinch when aiming down sights and extend Hold Breath duration.
Fast Hands	Reload, use equipment, and swap weapons faster.

Focus gives you an advantage in gunfights since you can maintain your aim on enemies even as you get shot at. This increases your chances of getting that vital headshot.

Fast Hands will always be important especially when engaging enemies since every second counts during a gunfight. Taking less time to reload or swap weapons may be what will save your life.

Best Ultimate Perks

Perk Name	Description
Ghost	Undetectable by UAVs, Portable Radars, and Heartbeat Sensors.
Hardline	Reduce Killstreak cost by one (1) kill. Reduce Scorestreak cost by 125.

Ghost may be the best perk in MW2 due to how common UAVs are activated. It's common for players to just look at their mini-map to find enemies whenever UAVs are up, so you can catch them completely by surprise.

Hardline makes it much easier to reach the higher-tier killstreaks that could possibly alter a match. This also makes obtaining UAVs incredibly easy, so you can activate one with each life.

Best Perk Packages

All-Around Perk Package

Base Perk 1	Base Perk 2	Bonus Perk	Ultimate Perk
Overkill	Scavenger	Fast Hands	Ghost

This Perk Package combines the best Perks from each tier to give you an extremely balanced loadout. You can use any weapon with this package, from shotguns to snipers.

Stealth and Tactical Knife Perk Package

Base Perk 1	Base Perk 2	Bonus Perk	Ultimate Perk
Tracker	Double Time	Cold-Blooded	Ghost

If you're the type to prioritize stealth and use suppressed handguns or even just a tactical knife, you'll want to take all of the perks that cover your tracks.

It'll be hard for enemies to detect you, essentially turning you into a hunter as you stalk your prey by tracking their footprints. You'll definitely be sneaking behind enemies and doing multiple Finishing Moves as a match goes on.

Close-Range Perk Package

Base Perk 1	Base Perk 2	Bonus Perk	Ultimate Perk
Double Time	Tracker	Quick Fix	Hardline

This Close-Range Perk Package is great for aggressive players who are constantly running through the map in search of enemies to fight up close. Combining Double Time and Tracker helps you chase after enemies easily.

Quick Fix and Hardline strengthen you even more since you'll most likely be taking back-to-back fights. As long as you win engagements, you'll be healed up throughout gunfights while quickly attaining killstreaks.

Sniper Perk Package

Base Perk 1	Base Perk 2	Bonus Perk	Ultimate Perk
Overkill	Scavenger	Focus	Ghost

Snipers will want to have two primary weapons so that they have a decent gun to swap to in case they have to engage an enemy up close. Focus will be important for having a stable aim at enemies, especially if they're on the move. Ghost will be vital for this build so that you can avoid getting hunted down whenever UAVs are in the air.

How Do Perk Packages Work?

New Perk Packages System Prioritizes Objective Play

Perk Packages is a new system in Modern Warfare 2 that changes your playstyle in a match as it goes on. Previous games had you equip three perks that were immediately available upon a match's start. The new Perk Packages system will let you have only two perks immediately available instead.

To get the rest of the perks in the package, you can either reach a certain minute threshold or get points during a match. Under this new system, Perks are broken up into three new tiers - Base, Bonus, and Ultimate.

Perks Don't Reset on Death

Once you've earned a Bonus or Ultimate Perk, you can keep that perk for the rest of the match. If you die, you'll respawn with the new Perks still active.
