Uncommon Infected

See also: Common Infected "Jumping Jehosaphat! What are these things?!"

- Coach

The Uncommon Common Infected, Uncommon Infected, or simply the Uncommon are new forms of the Common Infected introduced in Left 4 Dead 2. They have the same general weaknesses and health as most Common Infected, but there are a few differences that can affect how they're dealt with. Every campaign has its own unique Uncommon Infected.

The Survivors often comment on the Uncommon Infected, with the exception of the Worker Infected, noting their unusual attire and abilities.

Reflective Appearance
Each Uncommon Infected have reflective clothing, helping differentiate them from the regular Common Infected: These reflective areas can be easily seen by turning your flashlight on.
 * The CEDA Worker Infected have reflective areas on their suits
 * The Clown Infected wear reflective make up, which is arguably the least noticeable
 * The Mudmen's mud is reflective
 * The Worker Infected have reflective vests, which are most noticeable during the storms
 * The bands on the Riot Infected's arm, along with the word "Security" on his chest are reflective
 * Some Fallen Survivors have reflective bright red medkits on their backs

Tactics

 * See Common Infected's Tactics and Tips

Much of the same tactics for Common Infected will apply to most of the Uncommon Infected, as the Director will control them in the same way as normal Common Infected, and they will have the same amount of health. However, some of them may require new strategy to take down, which is listed in each Uncommon Infected's section.

Types of Uncommon Infected
There are several different types of Uncommon Infected, which are generally restricted to certain chapters of campaigns.

CEDA Worker Infected
"Guess those suits don't stop bites."

- Nick "Fireproof zombies. Hooray!"

- Rochelle

The CEDA Worker Infected was the first Uncommon Common to be announced and appear in the Left 4 Dead 2 campaign, Dead Center. Players will occasionally come across Common Infected wearing a hazmat suit (which appears to be of Level A (US)/Type 1 (EU) rating), which was worn prior to the person being Infected. When killed, there is a chance of them dropping a Bile Bomb (in which case it will be seen strapped to their side). When shot in the head, blood will splatter across the visor, and the sound of air hissing out of their now punctured hazmat suit can sometimes be heard. This would mean the hazmat suit was not punctured since the person became Infected, it is thought that the person must have been bitten before they suited up, but on closer examination under the neck, the suit is closed up. This may show that the areas around the limbs may have their own air pockets, leading to the air hissing sound. It is possible that the infected person may have been bitten in a different location. Through development of Left 4 Dead 2, the campaign the CEDA Worker Infected appeared in changed from The Parish, to extend to Dead Center, to being removed from The Parish completely, having been replaced by the Riot Infected.

Due to their hazmat suits they are resistant to fire, as in they do not burst into flame when in the middle of a molotov and incendiary ammunition just ricochets off them. If idle within fire for extended periods of time, they will die due to the heat. They come in two different varieties: yellow suits and green suits. There were also white suits, but these were only seen in the "Survival" trailer or spotted as ragdolls scattered about certain areas including the Parish.

Tactics and Notes

 * Collecting ten jars of Bile bombs from CEDA Worker Infected will earn the Achievement ROBBED ZOMBIE.
 * As they are immune to fire, do not bother using Molotovs on them. Either use firearms or a melee weapon.
 * If your primary weapon is loaded with incendiary ammo, it will not light them on fire, but still affect them as normal and will kill them in a few shots.
 * The CEDA Worker Infected makes it's second canon campaign appearance in the Left 4 Dead 2 DLC, The Sacrifice along with the Left 4 Dead 2 port of No Mercy, along with the Worker Infected.
 * If one looks closely at the CEDA Worker Infected, one will notice that the gloves are on the inside of the suit and the boots aren't part of the suit. Therefore, the suit is not sealed, proved by the fact that they are able to smell Bile bombs. This is against standard hazmat protocol as this allows unwanted agents into the suit,although that might be the reason they got infected at all.

Jimmy Gibbs Junior
"If the laws of nature allowed it, I would bear that man's children."

- Ellis "Dibs on Gibbs"

- Rochelle

Jimmy Gibbs Junior was a "famous" race car driver, writer of at least one autobiography from the South, and considered an idol in the eyes of Ellis and Coach. The survivors steal his race car to escape the mall. He is dressed in his racing suit and only spawns in the Atrium, with a 5% chance of spawning at all. He is mentioned by the Survivors briefly, saying things such as "If we see him, someone else is going to have to kill him". Nick makes a point of cursing his name regularly though, normally when something goes wrong with his car. This may be another play on the remake of the movie Dawn of the Dead, where the Survivors could see Infected versions of famous people that they knew from the mall. He has 1000 HP, no detachable limbs, and is fireproof thanks to his racing suit. He can also blind players with motor oil (similar to the Mud Men's splatter effect) and is not drawn to Pipe bombs or Bile bombs. Like any other Infected, he can be spawned using a console command. On his shoulder, he has the word GOODBYE, a reference to the vehicle and racing company GOODYEAR.

Tactics and Notes

 * Despite Jimmy Gibbs Junior's high health, headshots and melee weapons will generally kill him with a single attack.
 * As Jimmy Gibbs Junior is immune to fire, do not bother using Molotovs on him. Either use firearms or a melee weapon.
 * If your primary weapon is loaded with incendiary ammo, he will not be lit on fire.
 * When Jimmy Gibbs Jr. shows up as a Infected, Ellis may cry "NOO!!!!!!" This is due to how he is a fan of the driver.

Fallen Survivor
"That zombie's got something!"

- Coach "Is that Keith? Oh wait, no it's not. Never mind."

- Ellis

The Fallen Survivor was evidently a fairly well-equipped Survivor from the initial outbreak, but unfortunately became Infected later on. He appears in the DLC campaign The Passing wearing militia attire including a boonie cover and three ammo belts with a strap carrying visible Molotov, Pipe bomb, Pills and a First aid kit. He will run from Survivors upon being shot, much like the cut Special Infected, The Screamer, thus making him the least threatening Infected. However he will attack if you are covered in Boomer bile or have not shot at him yet.

Unlike the average Common Infected, he has an extremely high amount of health, to the point of being able to withstand multiple point-blank shotgun blasts. The only ways to kill him in one hit are explosive ammunition, melee weapons, the M60 or head shots. Head shots are very difficult to strike because you must actually hit his head or his helmet will deflect the bullet and startle him, causing no damage and making him run, making head shots near impossible. He is not immune to the lure of Bile bombs or Pipe bomb though; if a Survivor uses one, the Fallen Survivor will run to the location it is used. The Fallen Survivor has been seen wearing a blue, red, and green shirt.

He was going to be in Left 4 Dead 2 from the start, but was cut from the final version due to people having trouble in the beta version with him. He can be seen here, with mods. However, it is extremely glitchy and you will collide with his body, or rather, where his items are. If you pick up the items, which become invisible upon his death, it would make you lose your primary weapon, and get the HUD icon it would give you if you got a real Pipe bomb/Molotov/Pills/First aid kit, but you can't use the item. Picking your weapon back up, or another weapon, would cause you to lose his item. His character model is nearly identical to that of Whitaker. He can also be seen briefly in the "Zombie Survival Guide", running towards the Survivors in The Plantation.

A Fallen Survivor can carry any/all of the following items, which may be randomly dropped upon his death:
 * Molotov
 * Pipe bomb
 * Pain pills
 * First aid kit

Tactics and Notes

 * As The Fallen Survivor will run away when shot, use a melee weapon to kill him in a single hit.
 * Alternatively, if one of the team is carrying a Magnum or a M60, let them attack the Fallen Survivor first, as both weapons can kill the Fallen Survivor in one or two hits.
 * A Sniper Rifle or Hunting Rifle is also able to kill the Fallen Survivor in one hit in any mode other than Realism Mode.
 * Using explosive ammo with a firearm can kill the Fallen Survivor much faster.
 * A Bile bomb or Pipe bomb will lure him towards the location it was thrown in, even if he is running away.
 * Melee shoving the Fallen Survivor will temporarily stop his attempts at running away.
 * Whitaker's appearance is extremely similar to the Fallen Survivor, only uninfected and no blood stains.
 * He is currently the only Uncommon Infected to have a behavioral modification. However his higher health is likely due to all the items strapped to his person, as well as possible armor underneath his clothes.
 * When the Fallen Survivor attacks, it makes a clawing sound, much like a Special Infected, unlike the pounding sound other Common Infected makes.

Clown Infected
"That clown's bringing friends! Take him down!"

- Ellis "Kill every Clown you see!"

- Nick

Once a lovable entertainer, the Clown Infected is now a victim of the spreading infection. They wander around the Dark Carnival campaign and when they spot Survivors they will charge, calling other Infected in with their noisy, squeaky shoes for an attack. This does not actually spawn any new Common Infected. It only attracts idle Common Infected and Uncommon Infected nearby. Clown pants come in a variety of colors, including pink and blue, blue and white, and white and red as seen in the picture. If killed at a distance, all Infected following a Clown Infected will stop, swat at the air around its dead body, then attack the Survivors.

Tactics and Notes

 * A melee shove will honk the Clown Infected's nose. If done ten times, the player shall be awarded the CL0WND Achievement, a reference to Left 4 Dead ' s CR0WND Achievement. A single Clown Infected's nose can be honked up to four times in succession (due to four melee shoves killing it).
 * If the player ignites a Clown Infected who is leading ten or more Infected, they will be given the FRIED PIPER Achievement, a reference to the Pied Piper of Hamelin legend.
 * On easier difficulties, it may sometimes be preferable to let the Clown Infected attract a horde, since it does not add new Common Infected. This allows the Survivors to mow them down easily with their weapons without risking to check the corners in the darkness.

Mud Men
"There really are mud people."

- Rochelle "I tell ya, Mud People take all the fun outta Mud."

- Ellis The Mud Men appear in the campaign Swamp Fever. They are similar to the Common Infected, except that they are covered in mud and use this as camouflage. Mud men sprint on all fours low to the ground, although stumble back on two feet when shoved. They also run faster than Common Infected and are not slowed down by water. A hit from a Mud Man obscures the players screen with mud. This increases with successive hits, blurring the screen in a way similar to Boomer Bile. The Mud man's movement can actually be observed in Left 4 Dead. If a player enters an area that requires them to crouch, the Infected will follow them in, but instead of crouching, they will in fact crawl on all fours to get to the Survivor.

Tactics and Notes

 * Killing ten Mud Men who are in the swamp water will earn the Achievement DEAD IN THE WATER.
 * Shoving the Mud Man into the swamp then killing him also counts for the achievement.
 * It is worth mentioning that the Infected running towards Coach in the GameStop Pre-Order trailer is a Mud Man, therefore, it should have sprinted on all fours rather than just running, besides the fact that there are no Mud Men in Dark Carnival.

Worker Infected
When this unfortunate demolition crew received orders to tear down an old sugar mill, they were infected. Dubbed Worker Infected, these Infected populate the Hard Rain campaign. Workers are equipped with ear protection, hardhats, and reflective vests making them easier to spot in the downpour. Their ear protectors make them unable to hear Pipe bombs, and their blunt melee resistance is greater than usual. They also seem to be immune to bile bombs when Infected are not covered, since the bile alone on the ground uses the same attention-drawing programming as the Pipe bomb, a rather large oversight. They will be drawn to attack bile-coated Infected, still, but will re-target the Survivors once the affected Infected are dead. They are the only Uncommon Common to not have specific lines when spotted by a Survivor. They are also the only Uncommon Common to appear on every chapter of its campaign (the other four missing in either the first or last chapter of their respective campaigns). Though they are reported to be a demolition crew, they are referred to as "Common_male_roadcrew" in the files.

Tactics and Notes

 * Their hard hats offer no protection against bullets or melee weapons.
 * Worker Infected make their second canon campaign appearance in the Left 4 Dead 2 DLC, The Sacrifice and the Left 4 Dead 2 port of No Mercy, along with the CEDA Worker Infected.

Riot Infected
"Ah hell! Now they're bulletproof?"

- Ellis "Spin 'em round and shoot 'em in the back!"

- Rochelle

The Riot Infected appears in The Parish campaign. While human, they were members of a private security firm hired by CEDA to protect civilians. They turned into the Infected while still wearing their armor. This gives them immunity to bullets and to melee attacks from the front by blunt or sharp weapons like the Frying Pan and Machete, but not from behind. They are also vulnerable to Chainsaws regardless of area, and they are still harmed by fire and explosions. Riot Infected may drop a Nightstick upon death.

They don't have any Achievements linked to them, including "CRASS MENAGERIE", as they were formerly unavailable in the Australian and German version of Left 4 Dead 2. They briefly appear in the Zombie Survival Guide Trailer, even in the Australian version. Riot Infected were first featured in the demo and were part of the censorship controversy in Australia and Germany due to rules regarding violence against authority figures, however, they have been recently patched back into the censored versions, with some minor differences, having the word "SECURITY" removed from the front of their armor.

Tactics and Notes

 * Upon sighting the Riot Infected, the Survivors will sometimes comment on shooting it in the back. This is precisely how to kill them; they must be attacked in the back. Use a melee shove to stun them before moving around them. Sometimes, the melee shove will spin them around, in which case, movement isn't required.
 * Chainsaws retain their ability to kill the Riot Infected from any position, be it the front of the Riot Infected or from behind.
 * Molotovs and Pipe bombs will work as the Riot Infected's armor does not give it any immunity to fire or explosions.
 * Incendiary ammo upgrades will burn the Riot Infected just like how a Molotov would. Explosive ammo will kill the Riot Infected in a few shots even from the front. M60s or Magnums, however, will not penetrate the armor and, like all guns, will require a shot to the back to kill them.
 * The Riot Infected is significantly harder to defeat in the Mutation Headshot!, as the only vulnerable point of the Riot Infected is at the back of the head.
 * A riot police armor, similar to the one the Riot Infected use, are fire retardant in real life. However the CEDA Worker Infected already is the 'fireproof Infected', and resistance to fire would only make the Riot Infected even harder to kill.
 * A Riot Infected appears in the intro trailer of Left 4 Dead 2, when Ellis shoved him in the finale of Dead Center. However, Riot Infected can be found only in The Parish.
 * The Riot Infected appears even in the Australian and German Versions of the Zombie Survival Guide, despite being removed from the Censored Game Versions they have green parts instead of being all black.
 * In real life Riot Police armor is not normally capable of protecting against rifle caliber rounds unless the armor was upgraded with ceramic plates.
