eme Conditioning -->
Allows for extended sprinting time. Sprint time increased 200%. Great for combining with a ninja class, running around and knifing people in the back.

A great perk if you find no other use for Perk 3, sometimes you just need to sprint for that little longer bit of time…but you can’t, and sometimes you die because of it. This perk will fix all of that right up! Especially good for stealth classes to sprint across streets fast so no one will see you.
Available by default.

Steady Aim -->
My personal favorite perk 3, this gives some of those guns that just can’t quite do it at close quarters more than a chance. Makes hip-fire 35% more accurate, which is very, very helpful. It also indirectly makes long ranged fights easier from the hip. Range is how far your bullet can travel before it loses maximum damage and starts to decline in its damage, so if you fire out of range it will take more bullets to kill. But with steady aim, the fire will be more concentrated, so more bullets will hit the enemy target. This works well for assault classes, mainly. Thus SMG’s, Assault rifles, LMG’s, shotguns, and even mobile snipers are all legit. The great thing about steady aim is that it renews the greatness of hipfire. When looking down the sights, some of the screen gets covered up by the gun and the gun’s sights, and also it’s a TON harder to move. But with steady aim, you get full mobility with all of the firepower as before. Less accurate than aiming down sights? Yes, but it’s accurate enough for close quarters. Available by default. (Thanks to killer for the fix.)

Last Stand -->
Allows you to drop the ground and pull out a side arm if you are about to die. Very effective if you are quick. A person wont realize that they did not kill you and you can finish them off before they start firing again.

When you are gunned down, you pull out your pistol and get a chance at one last kill before you die. Will not occur if you get headshot sniped or something fatal like that. Causes many to twitch, but it may just get you that kill that you deserved. They gun you down, and start to reload/sprint off. But you’re still alive. You have your pistol out, you pop them before they can realize it and you get yourself one last kill before you pass on. Actually sometimes can benefit you, say you’re about to capture an objective and you get gunned into last stand, you can now protect that objective as people come along. It’s like being prone, but even though you can’t stand or move around, you have full turning mobility. If you want to exit last stand you can hold down a certain pre-set button, or after a certain amount of time you will die automatically. So why does it cause people to twitch? Say you get gunned down and they leave before you can shoot. Now their teammate comes up and gets an easy kill on you, and the person who originally gunned you down who deserves the kill has to deal with an assist. Not a bad choice of a perk, but there are better. It all depends on your preferences and your class type. For a camper this is stupid, you’re behind a wall, isolated and you get sniped, you’re not just sitting behind the wall with nothing to shoot at.

Martydom -->
Automatically drop a grenade right as you die in hopes of killing any enemies around your body at the time of death. Very effective if used in close combat indoors. Enemies will not have time to react and run away from your grenade right after killing you.

The grenade goes off 2.5 seconds after your death and when it spawns. It spawns on top of your dead body. For close quarters this perk is great and will earn you tons of kills, pointless at long range but at short range it’s great. Pisses many off, myself included, but it’s just a part of the game. You have to deal with it. Cheap, yes, as it requires no skill whatsoever. If you don’t care about cheap and just want kills, this is a great perk. But again, don’t use it for a camping class, as you will die and your corpse will explode in a mess of ashes which just makes you look dumb. Use it for perhaps an SMG or shotgun class, you know, close quarters situations.

Deep Impact -->
Normally, a machine gun has the power shoot through wooden floors, plaster walls, and even some fairly thick stone walls, but a weapon like an M4 does not. Or not as much. Use this perk to be able to shoot through walls with any weapon. Using this perk I advise shooting at walls and seeing if you get a white crosshair pop up indicating you hit someone, if it does, keep firing at the wall and you will kill the enemy without ever even seeing them. Note: Deep Impact does not add to bullet damage, it only lessens the damage penalty of a bullet that goes through a wall or other barrier.

Another great perk, I love this one for camp sniping. If there’s people hiding from you behind walls, then they’re screwed, there’s no place to hide. Great for any class really, you don’t have to worry about turning that corner and being at the mercy of the people camping around it. Especially great for LMG’s, spray a wall and watch the kill count go up, up, up.
This perk is available by default.

Iron Lungs -->
Increases the time a sniper can hold their breath while zoomed, to 8 heartbeats (200%) in-game. This should be every snipers favorite perk. (as oposed to the default 4 heartbeats).

Can only use for sniping, and even at that can only use when you are using the normal scope, as with the ACOG you don’t have to hold your breath. Normally you can hold your breath for four heartbeats, but with this perk you can hold for 8. I tend to find Deep Penetration more helpful than this perk. Usually this perk is only good if say, someone ducks behind a wall right before you shoot, so you stay steadied until they pop back out again. But with deep penetration you could just shoot straight through the wall. I don’t find this perk helpful in many situations, if I’m waiting for someone I just hold the scope close to around where they disappeared and I hold my breath for 3 heartbeats, let go, then hold again, let go…if you hold it for all 4 he spazzes out and you can’t hold again for like 10 seconds. Not advised by me, but many find it helpful, so if your personal preference suits it, then go right ahead.

Dead Silence -->
Makes you silent when you move. Perfect for stealth, but only in tactical or small games. For instance, let’s say you’re in a cage match. You don’t want them to camp for you and wait until they hear your footsteps and own you, so you just creep up behind them and get a free knife/headshot/challenge, and woohoo! So in small games its helpful, but also in tactical games like search and destroy. There’s not much action in this game type, so people are listening for sounds. But in big games like team deathmatch with respawns it’s mass slaughter and no one is listening for your footsteps unless they are camping at the top of a flight of stairs or something, in which this perk would benefit you less often than another Perk 3.

Eavesdrop -->
Allows you to overhear the enemy's voice chat within a 30 meter radius.

Pointless, don’t use it. The only thing good about it is that it only lets you hear nearby enemies speak, so you would know if someone is nearby. But that would only be if they were speaking, what if they didn’t have a mike, or it was turned off, or they just weren’t talking at the moment? Plus you would never hear anything important over their voice chat, it’s not like too many people plot out their entire attack plans over the chat. It’s ever so pointless, never use it except for fun perhaps.

Its pretty good. But the red dot sucks for the P90 IMO.

[ShawdowRaptor]

If no one remembers me, I also did this in the past as well. It feels good to be back! (=

nice one ?

Nice post. Good for the new users.

[Pickby]

Good list, with problems. Dragonov doesn't need SP, and jug was never recommended.

[Skillgasm]

On the last paragraph, when you were talking about eavesdrop you spelt "mic" as "mike".

Good guide well composed.
