Get to Know Your Tools
So you want to get good at playing the Infected in Left 4 Dead 2 eh? Well, you're going to have to start wtih the basics. Left 4 Dead 2 is somewhat unique in the fact that you have no real influence over what you will be playing outside of when you die and what else is in play. You can use these factors to your advantage to get a certain Infected, but we'll cover that later. First, let's cover the basic abilities, damage potentials, and the various other stats that your favorite undead crew has to offer you.
The Hunter
-250 Health
-Pounces onto a single surive to claw at them for5 damage per hit.
-Can do initial pounce damage up to 25 points based on distance.
-Knocks away Surivors around target being pounced on.
-Random chance to perform a back roll and be ready to pounce again when being knocked off a Survivor
-Makes a screeching noise when jumping or looking at a survivor while crouched. Makes a low growling sound while crouched. No sound while standing.
-Does a 6 damage claw attack, being beaten in melee only by the Charger and Tank.
The Boomer
-50 Health , the lowest of the regular Special Infected.
-Sprays a horde attracting puke on Surviors.
-Explodes when he dies. Sprays puke everywhere which can trigger a horde and knocks Survivors and Gas Cans back.
-Another horde cannot be summoned on the same player until the purple aura dissappears.
-2 damage claw attack.
-Common Infected summoned do 2 damage per attack.
-Constantly makes a gurgling noise. Makes a unique noise when spraying and clawing.
The Smoker
-250 Health
-Can "snipe" Survivors with his tongue from a significant distance to drag them until caught on an object or reaching the Smoker.
-Let's go over Survivor when tongue is broken by damage or the Survivor is melee'd.
-Survior that is being pulled as a short window of time in which they can shot at the Smoker before being rendered helpless.
-Does 3 damage while dragging, and 6 when the Survior is caught.
-Leaves a smoke cloud when killed which slightly impairs vision of Survivors. This cloud floats around him and can reveal his location if he is not hidden well.
-Does 2-3 damage claw attack.
-Constantly coughing. Makes a unique noise when sniping and clawing.
The Jockey
-325 Health
-Can ride a Survivor determining their direction. The Survivor can resist this by moving the opposite direction, but it does little more than slow the Jockey down.
-Can jump onto the Survivor's head from the ground, or fall onto it from above.
-Knocks Survivors around the target away when he latches on.
-Does 3 damage per hit while riding the Survivor.
-3 damage claw attack.
-If a Hunter pounces on his target it instantly refill's the Jockey's meter allowing him to strike again immediately
-Constantly laughs. Has a unique sound for riding and clawing.
The Charger
-600 Health, the highest of the regular Special infected.
-Can charge at a Survivor and pick them up to carry them with him. Stops when he reaches an obstacle and begins pounding the Survivor into the ground. Does not have to hit the target head on to pick them up. He can easily charge a Survivor off the side of a building or into water for instant death.
-The Charge sends any other nearby Survivors sprawling, sometimes off a ledge to their death.
-Does 10 damage to the Survivor when it hits a wall, and 15 with each pound.
-Has a 10 damage clawing attack, the highest besides the Tank.
-The only regular Special Infected who can not be stopped by melee bashing.
-Makes a constant mooing or mule like noise. Unique noise for charging and clawing.
The Spitter
-100 Health
-Can shot a glob of acid that spreads out and damage any Survivors that stand in it. The Infected version of a Molotov.
-If it hits a vertical surface it slides down until it hits a horizontal one.
-Damage is based upon how long a Survivor stands in it, ranging from 1 to 3 damage per second.
-When the Spitter dies it leaves a small acid spot where it stood.
-There is no distance limitation for the spit.
-The spit can destroy Gas Cans and cause them to catch fire. This is the only reliable way for Infected to destroy Gas Cans, making the Spitter the most valuable Infected in Scavenge.
-2 damage claw attack. (I need to confirm this.)
-Constanty making a hacking noise. Unique noise for spitting and clawing.
The Tank
*Tank strategy will be covered in a separate section from the other Special Infected, as his RAGE! meter limits his tactics to pure damage dealing.
-8000 Health
-Does 24 damage per hit.
-Can throw a projectile concrete slab. These can be shot down by Survivors.
-Can hit cars and other objects to fling them at Survivors. This can be DEVASTATING to a Survivor team if they are close together.
-Survivors can move faster than you at green health while shooting you.
-Survivors will ALWAYS try to burn your with Molotovs which will bring about a quick end for you. Watch out for this.
-If you do not have the Survivors in your sights or don't attack them, you will slowly lose control of the Tank. If you do not remedy this another player will take control of this. There is a brief pause when this happens when the Tank is completely vulnerable.
-Constanly growling and roaring. Causes the ground to shake. Has special music for his approach.
