Tier One Perks
I'm blue, da-ba-dee-da-ba-die, Tier one perks are one of the most useful, and often a hard decision when setting up classes. Here's the lowdown on all this tier's perks.

RECON

Recon is an incredibly useful perk that sadly, few people use because it has tough requirements for its Pro version, which is really useful.

LISTED EFFECT
Explosive damage paints enemies on the radar.

ACTUAL EFFECT
All launchers and grenades mark the target on the radar, and gives the direction where they're looking at to your whole team. Targets are marked for 12 seconds, unless they have Dead Silence, which reduces the mark to 6.

HOW TO USE EFFECTIVELY
Flash grenades. Flashes have a huge radius, and flashing someone counts as explosive damage. You can also use the XM-25 due to its large ammo pool and ease of use.

HOW TO GET PRO
Paint 120 targets.

EFFECT OF PRO
Gun damage paints the target.

PAIRS WELL WITH
Blast shield in case you accidentally flash yourself when you start out, but it usually goes well with everything. Marksman can be useful at acquiring targets before painting them.
For weapons, SMG/LMGs and Snipers are usually the best, as they either have a high rate of fire, or high accuracy.




SLEIGHT OF HAND

SOH is by far one of the most used and useful perks, for good reason: it removes one of the biggest hurdles in using heavy weapons: the reloads.

LISTED EFFECT
Faster reload speed.

ACTUAL EFFECT
Halves reload time.

HOW TO USE EFFECTIVELY
Just play normally.

HOW TO GET PRO
120 kills while using this perk.

EFFECT OF PRO
Switch weapons twice as fast.

PAIRS WELL WITH
Sniper rifles, LMGs, Launchers with more than one shot, and the MP412 for which it's absolutely necessary.





BLIND EYE

Rarely used, but very useful for support, Blind Eye is also a great way not to die in some cases.

LISTED EFFECT
Invisible to killstreaks

ACTUAL EFFECT
Automated killstreaks like sentries, AH-6s, Attack choppers, Pave Lows and support Ospreys never target the player. Player-controlled killstreaks like recon drones, reapers and predators, won't have a red highlight box/arrow on players with Blind Eye.

HOW TO USE EFFECTIVELY
Use this perk's power to shoot down air support, as they can't target you. The Stinger is by far the best way to do so.

HOW TO GET PRO
Destroy 60 killstreak rewards while using this perk.

EFFECT OF PRO
Launcher Lock-on time is reduced by 60%. This does not affect the Javelin.

PAIRS WELL WITH
SMAW and Stinger. Also any map with lots of openings for choppers to shoot at you.





EXTREME CONDITIONING
Great for crossing larger maps, and get to cover to cover faster.

LISTED EFFECT
Double sprinting length.

ACTUAL EFFECT
Exactly that.

HOW TO USE EFFECTIVELY
Run a lot, use light weapons, or the USAS, Skorpion and MP9, which also boosts your sprinting length.

HOW TO GET PRO
Run 20 miles. This is more time-consuming than hard.

EFFECT OF PRO
Obstacle-crossing is twice as fast.

PAIRS WELL WITH
SMGs and the USAS/Skorpion/MP9. Also maps with lots of cover, straightaways, and obstacles that needs to be crossed.





SCAVENGER
Incredibly useful if you plan on going on long killstreaks.

LISTED EFFECT
Retrieve ammo from fallen enemies.

ACTUAL EFFECT
Retrieve any non-explosive ammo from the enemy: This includes weapon magazines, throwing knives, underslung shotgun shells, underslung GL projectiles.

HOW TO USE EFFECTIVELY
Just play normally, but be careful when approaching corpses, enemies aren't always alone.

HOW TO GET PRO
Pick up 100 ammopacks.

EFFECT OF PRO
Start with more magazines for any non-launcher weapons you're using.

PAIRS WELL WITH
SMGs, any weapon with low ammo. Works great on Confirmed Kill, since you'll need to get to enemy corpses.
Tier Two Perks
Tier two perks all give very useful bonuses to your character, and are generally good in most situations. Picking one should be led by your playing style, and the type of weapon you use.

QUICKDRAW
Quickdraw is generally a good way to enter combat faster, especially with weapons that are inaccurate from the hip.

LISTED EFFECT
Faster Aiming.

ACTUAL EFFECT
Time used to switch to ADS is reduced by 33%

HOW TO USE EFFECTIVELY
All weapons have a different ADS time, use it with the slower ones to get an edge in firefights.

HOW TO GET PRO
Kill 80 enemies shortly after entering ADS.

EFFECT OF PRO
Lethals and Tacticals are used three times faster.

PAIRS WELL WITH
Snipers and LMGs. Tactical insertion is also much, much faster to use when coupled with Steady Aim, so you don't remain a sitting duck for too long. Also good for slow to set-up tacticals like the Trophy and the scrambler.




BLAST SHIELD
Rarely used due to the other perks being more efficient in general, this can be good in some situations.

LISTED EFFECT
Reduced explosive damage.

ACTUAL EFFECT
Damage from rockets, semtex, grenades, claymores, betties, C4 is reduced by 45%.

HOW TO USE EFFECTIVELY
If you're going for tanky support, such as recon Jugger or Riot Shield, as this allows you to survive a direct semtex.

HOW TO GET PRO
Survive 20 explosions.
EFFECT OF PRO
Duration of flashes and stuns reduced by 50%.

PAIRS WELL WITH
Freefire launchers, riot shield or juggernaut. Very useful against teams that are very explosive-happy.




HARDLINE
The thing you need for aggresive use of killstreaks.

LISTED EFFECT
Killstreak rewards need one less kill/point to unlock.

ACTUAL EFFECT
Exactly that.

HOW TO USE EFFECTIVELY
Aggressive play, in general, or heavy support, especially in gamemodes where scorestreaks are easier to obtain.

HOW TO GET PRO
Obtain 80 killstreak/pointstreak rewards.
EFFECT OF PRO
+1 point/kill for the streak for every two assists. Deathstreaks need one less death.

PAIRS WELL WITH
XP grinding, A drone/carepack, Predator, Chopper assault combo for aggresive play, or higher level killstreak rewards to get them more easily. Very useful with specialist streak, as it allows you to get the other perks faster.





ASSASSIN
Generally despised for some reason, it's actually very useful.

LISTED EFFECT
Cannot be detected by UAVs and sensors.

ACTUAL EFFECT
Heartbeat sensors, UAVs, Advanced UAVs, and Portable Radars cannot detect the player. Player has no thermal signature on thermal scopes. Recon drones can only flash the player, and no red arrow is displayed to give their position.

HOW TO USE EFFECTIVELY
Very useful for an aggresive sneak playstyle.

HOW TO GET PRO
Kill 20 enemies while a enemy UAV is online.
EFFECT OF PRO
EMPs and MOABs do not disable the HUD. Counter-UAV does not disable the radar. (MOABs will still kill the player.) No red reticle or name when aimed at. Marksman's effect is nullified.

PAIRS WELL WITH
Snipers, so you don't get bothered with being spotted or disrupted. Dead Silence + Shotguns or SMGs for aggresive sneaking.




OVERKILL
Double your gun, double your fun.

LISTED EFFECT
Carry two primary weapons.

ACTUAL EFFECT
Instead of a pistol, PDW or launcher, use a full primary. The first primary dictates the player's speed. The second primary can't be customized, but can accept a proficiency.

HOW TO USE EFFECTIVELY
Always use the lightest weapon in your first slot. Couple long-range and short-range for polyvalence. Always switch to your secondary when spawning, as it will use the full pick-up animation on your first switch, and it might kill you if you have to switch during a fight.

HOW TO GET PRO
Kill 120 enemies with your second primary.
EFFECT OF PRO
Second primary can be fully customized.

PAIRS WELL WITH
Snipers/ARs with SMGs/Shotguns. Or two similar weapons for maximum spammability. You usually won't need scavenger while using this.
Tier 3 Perks
The slightly-less important tier, but nonetheless quite useful depending on map or gameplay style.

MARKSMAN
Rarely used, as its advantage is somewhat minor, but it has its uses.

LISTED EFFECT
Identify targets at longer ranges.

ACTUAL EFFECT
Enemy names pop up faster and at longer distances, unless they have Assassin Pro.

HOW TO USE EFFECTIVELY
Long-distance is key here. So go on maps like Bakaara, Mission or Resistance, where there's lots of long shot areas.

HOW TO GET PRO
50 kills while holding breath. Make sure you hold breath WHILE firing!

EFFECT OF PRO
Hold breath for 8 seconds instead of 4 when using scopes.

PAIRS WELL WITH
Sniper rifles. And maps with lots of cover in dark or low-contrast areas. Goes very well with Recon, as you can spot targets more easily.




STALKER
Generally a very good perk, little to no cons to using it.

LISTED EFFECT
Move faster while aiming.

ACTUAL EFFECT
No movement penalty while in ADS.

HOW TO USE EFFECTIVELY
Excellent for strafing runs, especially with heavy weapons like LMGs.

HOW TO GET PRO
120 kills in ADS while moving.

EFFECT OF PRO
Claymores, IMSes and Bouncing Betties trigger 2 seconds later.

PAIRS WELL WITH
LMGs and auto snipers, as they have heavy movement penalties, and LMGs are very powerful when strafing. Good against teams that use lots of trigger explosives.





SITREP
Often dismissed due to its rather bland use at first, it's pro version is well worth it.

LISTED EFFECT
Detect enemy equipment.

ACTUAL EFFECT
Enemy killstreak rewards (including trapped carepacks), tactical and lethal deployments are highlighted in red.

HOW TO USE EFFECTIVELY
Useful on maps that are often heavily trapped, like Hardhat.

HOW TO GET PRO
Destroy 50 pieces of enemy equipment.

EFFECT OF PRO
Enemy footsteps are 4 times louder. Ally footsteps are four times quieter. Foils the effect of Dead Silence.

PAIRS WELL WITH
Supportive gameplay at first, but then becomes very useful for tracking enemies at medium-close range.




STEADY AIM
An excellent way to fight without that "ADS" thing.

LISTED EFFECT
Higher hipfire accuracy.

ACTUAL EFFECT
Hipfire spread reduced by 35%.

HOW TO USE EFFECTIVELY
Use weapons with high rate of fire, like SMGs, PDWs and LMGs. Can also be good for a quick close-range noscope, but very rarely.

HOW TO GET PRO
120 hipfire kills.

EFFECT OF PRO
Time needed to recover your ability to fire after sprinting is halved.

PAIRS WELL WITH
Any rapidfire weapon, or weapons with large spread in general. Of course, excellent pairing with Extreme Conditioning.




DEAD SILENCE
Become a ninja.

LISTED EFFECT
Quieter movement. Halves Recon duration.

ACTUAL EFFECT
Recon marking only lasts 6 seconds. Footstep sound is reduced by 90%, but Sitrep Pro counters this.

HOW TO USE EFFECTIVELY
Close-range fighting, as you can approach without being heard. Also good to move around the map unnoticed.

HOW TO GET PRO
50 Close range kills.

EFFECT OF PRO
Falling does no damage. Instakill pits will still kill you.

PAIRS WELL WITH
Assassin, of course, as it allows you to be incredibly stealthy. Extreme conditioning, too, as you can sprint across the map unheard. Excellent with shotguns on CQC maps.

if you use Blast Pro and riotshield it works as a tank for pushing

@Tc||Nyxx Er...what? The scrambler was removed?
nyx 3 Sep, 2018 @ 2:08am 
Feels as if we all refuse to acknowledge the fact that scrambler was removed. Otherwise specialist bonus would suck.

It does work, I haven't used much but the effect is very noticeable.
ImBulletm9 31 May, 2017 @ 9:35am

any_ridiculous_name 20 Aug, 2016 @ 3:12pm 
It was written in the internet...must be true ;)

Bunray  [author] 20 Aug, 2016 @ 3:01pm 
Nah, I checked it myself and on the wiki, the javelin has the same lock on time no matter if you have BEye Pro or not.
any_ridiculous_name 20 Aug, 2016 @ 12:48pm 
Pretty nice review! THX
However, "Launcher Lock-on time is reduced by 60%. This does not affect the Javelin." for Blind eye Pro feels wrong, since my Javelin got faster...I mean I did not measured it ;)
Bunray  [author] 28 May, 2016 @ 1:31am 
I barely use snipers, actually! I only got 500 kills on both L96A1 and Barrett 50.
