[No one's POV]
One person. One Infection. The two that caused to make the world we live in.. turn into utter shit. This virus defies anything anyone have ever seen. Sometimes it's airborne. Sometimes it's not. It mutates daily. Doctors and scientists all over are trying to cure it and yet.. they can't even pin it down. This virus is what being called either The Green Flu.. or The Infection.

This converted most humans who came into contact with it into homicidal and zombie-like beings known as the Infected. It seems to be a rabies-like pathogen and CEDA's designation of the virus as a form of influenza appears to be nothing more than a cover-up to avoid mass panic.

In terms of the Infection and mutation, the effects on the general population varied. The average Infected person results in becoming a Common Infected.

The Common Infected have deathly pale skin, yellow eyes with barely visible pupils or iris, hair loss and a weakened or weakening body structure to the point that a guitar can decapitate them with a single blow. The change in eye structure seems to have altered an Infected person's vision.

The Common Infected is not the only thing this Flu have brought upon this world. The Green Flu has the ability to mutate its victims into not just enraged hordes of Common Infected, but also powerful mutated Special Infected as well.

The Special Infected have higher intelligence than the Common Infected, as they are not attracted by car alarms or loud noise and are able to run away if required to set up an ambush. They are also more aggressive than the Common Infected, as they will actively attack Survivors rather than passively sitting in a stupor until disturbed. Usually, most of the time, Five Special Infected are mostly seen by Survivors. The most dangerous ones out of them would be the Tank..

Mutated through infection, the Tank's only strategy is brute force. Find the Survivors. Pummel them to death. Repeat. Healthy Survivors can run slightly faster than you. Try to trap them in tight areas, or use a thrown chunk of concrete to stun them.

The Tank is arguably the most powerful Special Infected in the game along with the Witch due to his combined brute force and agility. Unless a team works together to take this brute down, it can wipe out entire squads with or without help.

Speaking of the second most powerful Special Infected..

[The Witch]

Witches only want to be left alone so they can enjoy a good cry. They hate flashlights and loud noises, but what they hate more than anything is being shot at. If you hear the Witch's tell tale sobs, turn off your flashlights and try to sneak around her. If she starts to get angry, her growl will let you know she's close to attacking.

The Witch is highly sensitive to light and the close presence of uninfected humans. She is completely unresponsive to Infected and the passage of nearby bullets.

When alerted to the presence of an uninfected human or flashlight, she will look in the Survivor's direction and make a low warning growl: this signals an incipient attack. If the Survivor backs away a fair distance or is no longer in sight, she will gradually return to her wailing state, taking longer if the intensity of her warning growls is high. However, if the Survivor is still nearby, she will slowly stand and flail her arms in a threatening manner; if the Survivor does still not move, she will single them out and run at incredible speeds. She is able to incapacitate her victim instantly whereupon she frenziedly slashes that person with her clawed hands, only stopping if either she or the victim dies.

[The Hunter]

Hunters are primarily identified by their distinctive and intimidating growl, or the screams and snarls they emit upon sighting a Survivor or whilst attacking. Hunters are the only Special Infected who do not make any noise while in a passive state.

Extent of Mutations
The Hunter is the least visibly mutated Special Infected and superficially resembles a Common Infected. It has yet to be explained how the Hunter's mutations onset, whether it be genetic, biochemical, or a Hunter-specific strain of the virus, but the mutations seem to be sex-linked as only male Hunters have been observed. The Hunter's reaction to the Infection has granted him a dramatic increase in lower-body strength.

While not creating massive muscle growth like the Tank, this added strength has given the Hunter the ability to repeatedly jump and pounce from long distances and rapidly scale the sides of buildings with ease, as well as toughened his legs in order to withstand the great distances and heights he can achieve.

They are well known for their pouncing attacks. Once they pounce onto an un-expecting Survivor, they will use their sharp claws and aggressively claw into your chest, hips, torso and ribs, tearing you apart chunks after chunks.

[The Smoker]

The Smoker is a Special Infected characterized by his extremely long tongue. The Smoker's tongue can be launched out of his mouth at high speeds towards a Survivor, and when it reaches one of them, it automatically wraps around the target's body and drags them back towards the Smoker, where he begins clawing them. If an obstacle is in the way, then the tongue tightens and begins to choke the target.

Extent of Mutations
The Smoker has been heavily mutated by a strain of the Infection and frequently makes high-pitched rasping and coughing noises that can alert Survivors of its presence. Though he resembles most Common Infected, he is taller, more durable, and his skin has become covered in growths that cause little spurts of green smoke and blood to ooze out when shot. It is said that the smoke he expels gives off a putrid smell, but it is otherwise harmless. The left side of his face is bloated and appears to be covered by a large tumor.

When constricted, Survivors have a brief moment (1-2 seconds) to shoot the offending Smoker before their arms are ensnared by the tongue. If they fail, the Survivor is helplessly dragged off, and will take damage until they die. Survivors can be rescued by killing/shoving the Smoker, or by attacking and breaking the tongue. The Smoker's tongue will slowly grow back after being cut off and can be used to attack again after 30 seconds.

[The Boomer]

The Boomer is an extremely bloated Special Infected. Their mutation has caused them to produce immense quantities of bile which they attempt to vomit on the Survivors, temporarily blinding them and summoning a small Horde. Though fragile and slow, the Boomer can be dangerous to a Survivor team whose health or combat abilities are compromised.

The fat, slow zombie vomits a thick bile with two side effects: It blinds Survivors, and it attracts hordes of Infected. When Boomers are killed, they explode, showering bile on anyone nearby.

There is no absolute telling how many these things are and yet..they continue to roam this planet.

[Somewhere else]

*Your home*

A young adult male was walking in the woods near their home they live in with an older male with brown hair in hiking clothing. His name is Y/n Solace.

*what you are wearing*

*Gloves and shoes included*

Y/n lives with his father alone ever since his mother died from an incurable disease when he was 15 years old. then felt a prickly on his arm as he sees a mosquito trying to drink his blood.

Y/n: damn it..*smacks arm that has the bug*

D/n(Dad's Name): *looks back to his son* You keeping up, kid?

Y/n: Apart from mosquitoes constantly trying to bite me..I think I'm doing fine.

D/n: Nature can be a bitch a times, but without it, no one would survive.

Y/n: Yeah.

The Father/Son duo continued their trail for a few extra minutes until they stumble upon a gun shooting area.

A "Growl" was heard as Y/n turned around to see where that noise was coming from.

Y/n: Huh?

D/n: What is it?

Y/n: I could've sworn that I heard an animal nearby.

D/n: Not possible. These wood's haven't shown an animal within the past 3 weeks.

Y/n: Now that you said it, I haven't seen one deer in ages.

D/n then stopped walking and turned to Y/n as he wanted to ask him something.

D/n: You got your twin revolvers, right?

Y/n: Yeah.

Y/n reached to his holster and pulled out a pair of twin revolvers from the behind gun holsters from his back.

Y/n: Yeah. What for?

D/n: We're about to do some target practice. You said something about working on your recoil, right?

Y/n: Yeah. *looks at the revolvers in his hands* These things really pack a punch when they fire.

D/n: That's why I'm training you to withstand the powerful recoil with one hand while wielding two.

Y/n: Okay.

With that, Y/n then got to shooting the target's. At first, his wrist starts to strain from having to use his strong revolvers with both hands, but he eventually pulled through.

[Timeskip]
It was getting late as the father and son placed their weapons back in the ground. Y/n was about to reload them with new bullets, when the young male was cut off when he heard growling again.

Y/n: What the-

Y/n turned to where that sound was at, but was cut off by a bine-chilling scream and something pouncing onto him, sending him to the ground. He felt his chest and hips being clawed into and ripped off peeve by piece, causing him to scream in agony.

D/n: Get the fuck off him!!

D/n aimed his rifle and started shooting loads of bullets onto the Hunter as it staggers back. Y/n with one arm took out his revolver and starts shooting the agile zombie too, until one bullet went through the head, killing it.

Y/n: Oh, God.

D/n quickly runs toward his injured son and gets out a first aid kit..

He sat him up, despite the pain and managed to bandage him up to full health. Though for mythical reason after being bandaged, Y/n feels completely healed.

[Y/n's health: 80%]

Y/n sighed a breath of relief as his wounds are now healed.

Y/n: Thanks, Dad.

D/n: Sure thing. *helps him up* So that's a Hunter, huh? Never thought that u see one near or home. We better head back.

Y/n nodded as the father and son then walked back to their home to get away from whatever else might be here.

[Nighttime]
The duo traveled back to the house, wary if whatever could pop out

Y/n: This is really getting strange. Ever since this Infection showed up. Everyone became erratic towards one another. Even my own friends distanced themselves from me.

D/n: CEDA not even helping in the slightest. Leaving us to find for ourselves.

Y/n: So, what can we do, dad?

D/n: We make the best of what we have

A "Click" sound was heard from both their ears.

D/n: The hell?

Y/n: What was that?

The father heard something break on top of him as he looked up to see Green slime falling onto him.

D/n: *groans in disgust* Ugghh..the FUCK?!

Y/n: *perplexed* Dad?!

A

n echoing roar was sorted throughout the forest. Multiple footsteps were heard as they turned to see a large horde of infected coming their way. Y/n takes out his revolvers and instantly started shooting at them. D/n gets his gun and opens fire on the Horde. Unfortunately, he started to get overwhelmed as one of them knocks his gun away and they push him to the ground, hitting, biting and kicking him all over.

Y/n: *sees his father down* Dad! I'm coming!

D/n: *holds his hand forward; gestures him to stop* No! You need to get back to the house!

Y/n: *shoots at the Infected* I cannot just leave you here!

D/n: NO!! YOU MUST SURVIVE! No reason to die with me.

He reached inside his shirt and pulls out multiple lines connected to one another. Y/n realized that his father had some Grenades around him and was gonna blow himself up rather than turn into a Common Infected. The older male male then got bitten hard on his neck, drawing blood as he chokes on it.

Y/n, knowing that his father wouldn't be saved even if he did fought back, heeded his words and ran back inside the house as the zombies devoured the man alive before the grenades finally detonated, destroying the Horde and the father in the process.

[Y/n's POV]
I..I can't believe it. My father is gone. The only family I had was taken from me. I sat down with my back on the living room door

Y/n: Okay..okay. I am alone against these things.

I calmed myself down after a few minutes and went downstairs to gather supplies. I could survive if i stay on here, but food would run out and i would have to get more eventually. I went to the living room when I saw packing the most necessities for survival. I saw a very large container box next to the TV.

I opened it and saw the contents that was inside.

Y/n: Wow..*sees a paper under the top opening of the box* A note?

I pulled the paper off as I read what is there:

"Hey, kiddo. If you are reading this, that means that I am dead from the Infected or CEDA forces. Inside this large case will help you survive throughout the apocalypse outside. The rifle is highly customized to fix your standards. Grenade Launcher, Flashlight/Laser Sights, Extended Mags/Fast Mags and Hybrid Sights. This Rifle will be your best friend. The Green Canisters you see are filled with bile from a zombie called Boomers. Throw them at a area and Zombies will run at it like a mouse with cheese. You may meet some other survivors and they'll might shoot you on sight, so always watch your back. I'll be watching from the skies."

Love, your dad.

Y/n: Dad...

[A few minutes later]
After I was done packing my necessities, It was finally time for me to move out in the world. Carrying the customize rifle my father left me, I started to walk to the front door, overlooking to see Infected roaming around.

Y/n: Out in the open.

I looked at my waist to see one of the Pipebombs strapped on and decided to put it to use. I took it off my hip, opened the door, lit up the fuse and threw it at the group.

Y/n: Chase that, you rotten sacks of shit!!

The high pitched, beeping sound had an immediate effect. The infected ignored new and ran towards the pipe bomb, each in a frenzy to get closer to it. After a few seconds, the pipebomb exploded, blowing the group of Infected into chunks of flesh. I walked out of the now safe area with my travel pack on my back.

Y/n: Okay. Now..*looks back at the soon to be former home* Time for me to continue on.

I started walking away from the forest to see of a town is nearby. Hopefully, there should be some people still here.

[And that's it for the prologue. I know I said I post it this weekend, but I got caught up in work. Anyways, I hope you enjoy.]

Also another thing: What chapter in the left 4 dead(first game) do you want to meet the 4 original Survivors in? Let me know in the comments.
