Hello people of FanFiction! Here I am to present a crossover of L4D & TF2! There aren't many stories over this crossover and I don't know why. I for one think it would be interesting to see how the mercs deal with the zombie apocalypse. So my friends (Who also came up with the title) and I wrote this!

Key notes: The first two chaps are L4D-centric, then it's TF2-centric, and then a combination of both. It's the RED and BLU team of 2009 (Or 2010. I don't know what year it is in the L4D universe.) The L4D2 Survivors will make an appearance in case you're wondering. And the story contains OCs.

Disclaimer: L4D and TF2 belong to Valve.

Edit: This story is an AU, I apologize for not informing you of this early on. And in this chapter you'll find that Luigi has a little friend with him, a puppy he and his brother found in my L4D story during the Death Toll campaign. Also, it has come to my attention that I put too much spotlight on the OCs and not on the Survivors. I apologize for that too, and while chapters are going to be in the OC's point of view, there will be ones featuring one of the Survivors. Take for example this re-edit of chapter one in Zoey's POV.

Enjoy!

(P.S. I did put spotlight on one OC, but only because she was the female OC I was talking about in my last author's note that will be replacing Rae, and I wanted to give you guys a taste of her to see if you will like her or not.)

Chapter 1

The sun dipped behind the horizon in a great ball of fire. Six figures crowded around a sleek, black Lexus. They had a good run with the car before it ran out of gas. A gruff biker with more art on his arms to combat a museum angrily kicked one of the tires.

"I hate cars." he announced.

Beside him, an old man clad in an army uniform and the group leader, rolled his eyes.

A young woman who enjoyed lifting the group's spirits with jokes pulled a notepad out of her pocket. "Cars," she echoed, jotting it down.

Next to her a soft-spoken, but positive business man leaned over to sneak a peek at the writing before shaking his head with a chuckle.

The biker glared at her. "What did you write about me, Zoey?"

"Relax, Francis." Zoey waved an absentminded hand. "I was bored, found a notepad and pen, and decided to write down all that you hate. See?" She held it up for him.

All the things Francis hates by Zoey.

1. Bill's plan

Bill, the old war veteran, glowered at Francis who grinned sheepishly.

2. Boat lawyers (Lolwhut?)

3. Cops (Even though he tells us to act like them whenever we meet people)

"And for good reason too!" Francis defended himself. "People will do anything for cops."

4. Ellis's hat

5. Lady Gaga

"I've never said I hate Lady Gaga, whoever that is!" Francis objected.

"Yeah, you did, when we were listening to Alejandro in the car." piped up another young woman munching on a bag of Doritos. She had brown hair up in a messy ponytail, a light tan skin complexion, and brown eyes. She wore a dark blue shirt that had french fries saying "Bonjour" and a taco saying "Hola" on it, a cream colored scarf, a necklace with a red fox charm on it, gray skinny jeans, and black buckled lace up combat boots.

"Oh."

6. Louis's good feelings

"Hey!" Louis, the business man, exclaimed after reading this.

7. Stairs (Bill hates these too)

"Damn straight," Bill muttered underneath his breath.

8. Teenagers

9. Cars

Francis blinked. "Do I really hate all of that?" he asked in surprise.

"Yep," everyone answered simultaneously.

While the biker stood there stupefied for a minute, Bill decided to bring up the current situation. "Okay, people. Any ideas on what we should do?" he asked.

"Well," Zoey began before anybody else. "The car's not going to magically refill itself on its own. We're better off walking."

"She's got the right idea," Louis agreed. He turned to the girl. "Sabella, could you pop open the trunk?"

"Sure thing, Louis!" she chirped through a mouthful of Doritos, reaching into the car to tug at the latch.

Zoey glanced over toward the last and final member of the group. Luigi was a sixteen-year-old boy with wavy brown hair, fair-skinned, and had bright blue eyes. He wore a Super Mario Brothers shirt, jeans, and black Vans. He was on the ground rolling around a small ball for his black Labrador puppy he named Tycho to chase around. She heard him laugh softly while he wrestled with his pup for the ball. The former college student reached into the trunk to pull out a katana caked with dry blood.

"Here," Zoey placed the weapon down beside him. When Luigi thanked her with a simple nod of his head, she asked, "Are you okay?"

"I'm fine," he murmured coolly without looking at her.

Zoey felt a bit stung by the tone of his voice. She knew they had a fallout back in Rayford, but one would think Luigi would've gotten over it by now. She decided not to press the matter anymore and retreated. While on her way to retrieve her hunting rifle, she felt a hand on her shoulder and turned around to see Bill.

"Give him time," he told her. "It must be hard for him after losing William."

A wave of grief washed over Zoey at his words.

After escaping Millhaven by train, they had come to a stop in a small Georgia town called Rayford. Bill was set on finding a sailboat so they could go to the Florida Keys and not have to deal with the Infected anymore. At the time, Zoey had been majorly against it, and she still was, but she begrudgingly went along with the plan. She knew the second her brown eyes fell on the bridge they'd have to raise to move a sailboat they found that it wouldn't end well. Neither of the Survivors had known just how fast luck would turn against them. A generator went out, stalling the bridge, and trapping them there while the biggest Horde they had ever faced rained down on them. To make matters worse, the Horde had been accompanied by four Tanks.

It was there, on that noisy bridge in that small town, where the Survivors had lost hope. Even Louis's positive morale had been thrown out the window. Zoey just couldn't believe at how far she and her ragtag group had come only for all their struggles to end like that. Bill, on the other hand, had a different idea. She remembered watching from the corner of her eye as he lit a molotov with his cigarette and realized with a jolt that he was going to risk his life restarting the generator.

But it hadn't been Bill leaping down into the midst of the Horde and capturing three of the Tanks's attention. William had gone instead despite Bill's shock and Luigi's heart-wrenching wails for his big brother to stop. The seventeen-year-old hadn't listened and they eventually lost sight of him. When they had gone to bury him, they were shocked to discover his corpse was missing. After getting over their initial shock after the discovery, they had grieved greatly before leaving, but even after a couple of days had passed since the tragic incident, Bill was still feeling regretful and Luigi continued to mourn.

"Then it's a good thing you let him keep that puppy," Zoey said. "Tycho has kept him from grieving too much."

Bill merely nodded before raising his voice to inform the others that they needed to get going. Quickly grabbing her hunting rifle, she raced after her teammates until she fell in step beside Louis.

"I hate walking," Francis muttered.

"Walking," Zoey pulled out her notepad and wrote it down.

"Dammit, Zoey!"

Clouds flitted across the star-filled night sky, occasionally blocking light from the full moon. Bill peered out from behind a tree, shining his flashlight and illuminating the dirt road they were traveling down. A few Infected lingered here and there. Francis eagerly picked them off.

"Come on," Bill gestured for his companions to move out.

The Survivors poured out from the trees with Bill leading and Francis guarding the rear. Sabella helped Louis along, his injured leg bothering him. They had to be extra cautious since the trees surrounding either side of the road provided good places for Infected to hide. Zoey gave a startled jump when growling filled the air. She turned around to see Luigi trying to shush Tycho, the black Labrador puppy glaring at something in the distance.

"Francis, look out!" Luigi suddenly shouted fearfully.

Francis whipped around just as a Hunter leaped out from the trees toward Francis. The biker dodged out the way while smacking the hooded creature in the face with the butt of his auto shotgun. It snarled as it staggered before quickly dropping back into a crouch. However, before it could pounce, bullets pierced its flesh. It toppled to one side and laid there motionless. Francis gave the corpse a satisfied kick before turning back to Luigi.

"Thanks for the warning."

"Don't thank me," Luigi smiled down at Tycho whose tail began bumping against his arm when he scratched his pet behind the ear. "Tycho was the one who knew the Hunter was there."

"He's like our little Special Infected alarm clock," Louis joked.

The others gave good-humored chuckles. Zoey picked up the pace until she was walking beside Sabella. The brown-haired woman was munching on another bag of potato chips; this time they were Lays Sour Cream and Onions. Feeling eyes on her, Sabella looked up at Zoey and looked down at her snack, looked up, down, up, down, up—

"It's fine, I don't want any." Zoey chuckled.

"Oh, good." sighed Sabella gratefully. "So what's up?"

"How long do you think Luigi's going to be like this?" Zoey asked, lowering her voice.

"I dunno," she answered truthfully before smiling. "Don't worry though. He should be back to his old self in no time!"

Zoey fell silent as she contemplated this while Sabella shoved a handful of chips into her mouth. Then after a while the college student spoke up.

"Do you have any idea where William's body went?"

Sabella paused mid chew, her face saddening. After swallowing, she replied, "It's hard to say. I highly doubt he was dragged off by an animal, and I don't think Infected eat each other. He may have turned."

"Then he might have humanity like their brother does!"

"If he did then why didn't he come find us?"

Oh. Zoey hadn't thought about that.

Sabella heaved a great sigh. "I'm not hungry anymore…" she murmured and rolled up the Lays bag before stuffing it into her backpack. She shot her fellow Survivor a sorrowful glance. "I'm tired of this." she whispered brokenly. "Why can't this just end?"

Her throat tightening, Zoey looked off into the trees, unable to meet Sabella's gaze. Neither talked, the silence only broken by the sounds of their feet crunching against the dirt road, grunting of Infected hidden somewhere in the coppice, crickets chirping, the occasional howl of a coyote, and leaves swaying in the wind.

"One day," Zoey began, her voice filled with conviction as she lifted her brown eyes up to stare at the stars. "I truly believe the world will go back to normal."
