Killing Floor is a survival horror total conversion set in London, England.

In a laboratory under the city, a series of human experiments in cloning and biological augmentation are being conducted by the employees of "Horizon". Horizon is a BioTech corporation formerly employed by the government to do the R&D on a top secret series of synthetic combat drugs which would enhance the effectiveness of soldiers in the field.

Horizon's funding was cut, when their practices were deemed too immoral even for such a controversial project, but the research didn't stop. Funded by private money from the deep pockets of Horizon chairman and research scientist Kevin Clamely, tests continued in a more...private location.

That was until something went wrong. There were reports that the lab had been comprimised; that the subjects were behaving abnormally...then, silence.

Several days later, twisted shapes began to emerge from the confines of the lab into the city above.

Yes, it is true. My friend the developer whose name I will not divulge, as well as myself, have made some major improvements to the game. We have added more and newer weapons, and a new character which I called the 'Infected'. The additions are displayed below (namely the new textures of the Killing Floor mod characters):

1. Bloat

When you DO not know anything about the subject just DO not talk about it , or read the description : it says that it was released in 2007 (even if 1.0 was released in 2005), and KF retail (the game, not the mod) was out in 2009.

What is your point here?
TBH this don't change the fact that KF Mod WAS MADE BEFORE KF Retail.

This is Alex Quick's first Killing Floor mod. It isn't the retail version! I personally like the mod, but isn't too keen on the retail version. I just wish Tripwire will allow us to expand the mod seeing it is a by-product of Unreal Tournament 2004.

As for the Out Of Hell mod, I didn't know anything about KF people discouraging Chicken+Ribs from completing his mod. Sorry to hear that. Out Of Hell is another good mod. Not sure if it has MP which makes a big difference.

Well, I can honestly say I have no respect for the KF team, now realizing what they did to the Out of Hell developer, they went and loudmouthed at him and said his mod was bad, as well as giving him tips on how to make it better, telling HIM what to do. And to add insult to injury, he went through a deep wave of depression, and STILL managed to release the mod and keep up with the communities demands. Killing Floor kept saying how they were superior after they got a mod team, while they were jealous and afraid their mod wasn't going to be good

**** you self-righteous faggots.

I think you're very confused. Since I have some experience with this I'll help you out.

...they went and loudmouthed at him and said his mod was AWESOME, as well as giving him KUDOS FOR BEING AWESOME, telling HIM "YOU ARE AWESOME". He went through a deep wave of depression, which was sad but happened after both OOH and KF Demos had been released. Killing Floor kept saying how they NEEDED AN AWESOME PROGRAMMER because it would be pretty rad to have more than 2 people while they were TOTALLY PUMPED and HIGHFIVING their mod wasn't EATING CHILDREN IN THEIR SLEEP, because that was always a concern with us.

Where can I read the ******** they said? The Out of Hell developer is pretty chill despite his mod running like crap on my setup.
