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

Great mod once you get use to the no crosshair thing just would be better if there was a larger player base or atleast a single player campain cause it seems with UT2004 not really much people play proberly they prefer the newer version of the unreal series

This is the first time i play this game, so i just wanna ask:
1) Is there's no crosshairs?
2) How do i use the iron sights of the basic pistols and some guns?
3) How do i find the gun-seller in each maps?
Thanks and sorry for being a noob, ya?

1. No crosshairs. If there was a crosshair, it would always be in the middle of your screen - that's where you need to aim.

2. Short range weapons have no iron sights, because it's unnecessary.

3. To find the trader, just follow other players.

One more question: What's the difference between the retail version and the mod?
