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

Killing Floor, such good times. I'm a Killing Floor veteran myself, got in here when KF 2.0 got released and saw how it was being updated to 2.5 right at the start, then to 2.52.

I tried the first version first though, it was great. Then I tried KF 2.0, it was different from the first one but it was great too. Then the next versions and so on...

Killing Floor was such a great mod, now it was a good game and now it's a..."fun" action zombie-killing game. I know there are no zombies there, but damn.

This mod was way more about Survival and Co-op, about Horror and Paranoia. The official KF and KF2 is more about action and having fun in such a silly way.

I miss the old Killing Floor and I guess I'm gonna get some "oh shut up stupid veteran your al the same" comments soon enough, still...

For all the Killing Floor veterans out there;
I salute you, comrades.

What exactly are you looking for? You know you can edit the mod so as to increase or decrease the number of zombie spawns in each spawn times.

It has been a while since I posted any comments here, and that is because I have had no problems until now.

A few days ago I uninstalled UT2004 and killing floor (version 3) and now whenever I try re-installing KF3 it says that it cannot unarchive newtextures.tex (or whatever it is called). I tryed redownloading it from the link you gave me but it still doesn't work.

Killing Floor 2.52 does still work though.

Sorry for the late reply. I don't know. Maybe if you use the Windows compatibility option then it might work. Anyways, send me a message if you need anything else.

Yeah, it's the third floor window.
Still have no idea about the white screen though...

Anyway, as far as my editing and modding knowledge goes, I only ever managed to make a building a playable unit in age of empires 2(that isn't against the code of conduct is it? Because i'm not really advertising)
All in all, i thank you.

P.S. Just keep in mind that you need to give credit to whom credit is due (if you are editing a map that's not yours).

If the game provides you with an editor and it is considered as moddable, then I would think that they intends you to be creative and make some editing to their maps. Therefore I wouldn't consider it as a breach of the code of conduct.
Anyways, there are a few re-coding you need to do on your UT2004.ini file in your C:\Program Files\Unreal Tournament 2004\System folder in order for you to use the Unreal Editor for KFMod20. Let me know if you need help with it.
