Just a couple of things you need to know before reading this story:

The story is probably going to drift waaaaaaaaaay off Left 4 Dead's originality and will seem extremely weird at times.

Rated T just in case, will have swearing (thanks for that Nick) blood, but also 'sexual' themes and scenes will be coming up so I might change rating.

It's set in Swap Fever with all 7 survivors (R.I.P Bill) meeting and parings will be there. XD

Thanks you for reading it, even if you don't review means a lot for people just to read it!

-Prologue-

Help me understand why you're giving into all these dark desires, you're lying to yourself again. Suicidal Imbecile.

Everyone has their day when they wake up, slime crawling in the back of their throat, nose full of nothing but endless mucus and an itching throat that feels like someone is purposely scarping sandpaper down it. Everyone has their day when they get sick.

It's never nice being sick, for the first few insufferable moments you feel wonderful because being sick means you don't have to drag yourself into school, or hide a million tissues in your purse for work so all the papers on the desk aren't drowned in mucus and drooling saliva. Yet, just having a common cold can be horrible.

That's what they told everyone, it was just a common flu, something that would pass eventually. That's what the Civil Emergency and Defense Agency(C.E.D.A) told everyone. C.E.D.A was supposed to protect and assist in any natural or manmade disaster in America, to stop the Green Flu epidemic.

C.E.D.A was doing that for a while, containing the first outbreaks of the flu, the first victims were immediately put into hospital, full of other sick patients. That was C.E.D.A's first bad move. The Green Flu wasn't just like a common cold, it was a smart virus. Something that knew how to grow by infecting others in all sorts of ways.

Unsuspecting doctors and nurses working with the first victims of the Green Flu had no idea what they were getting themselves into. Before they even knew it the 'infected' patients began biting them, ripping their very skin apart and allowing the virus to spread.

Wasn't long before the whole world was now on alert from the growing epidemic, thousands of people who weren't immune succumbed to the virus quickly. It was now a matter of kill or be killed. The peculiar thing was after the infection spread anyone working with C.E.D.A was nowhere to be found. There were some who wore hazmat suits that had been infected, even some officials of C.E.D.A were found to be infected as well but the general organization was gone. Wiped from the Earth like they never existed.

Which begged the question, what would they be hiding from?

Some say that C.E.D.A were the ones toying around with virus's and they were the ones that made caused the outbreak. While others wondered if they were an actual organization.

One person came up with an interesting theory though, they said that some virus's or strains can have what someone would call a mother and father strain. Together the strains could create such a virus. Usually the first people to be infected would be the mother or father strain but in this case it wasn't.

What if C.E.D.A had been experimenting?

Maybe there was someone out there with one of the parent strains and they started this all?

It was just theory but it sounded more accurate than most, there is only one way to find out if that theory is true or not, there is only one way to find the truth.

But sometimes that theory can come knocking right on the safe house door, sitting right next to you, maybe even...kissing you.

Disconnect and self destruct one bullet at a time, what's the rush now? Everyone has their day to die.

Please no flames
