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.

It's nice that Alex is okay with this, but I really don't see why anyone would be playing KFMod over retail KF.

maybe ppl will play kf 2.51-R cuz there's no epic fail spawn like the retail =P
is it good to see zombies spawning behind u? naaaa that's sucks...
killing floor is mod requires more tactical stuff. In kf mod zombies won't cheat to kill u... in kf retail zombies cheat in spawning, running, hit collisions (like the husk), and more ****** stuff...

I could forgive them some gameplay problems but KFGame doesn't even have any skins... let's be honest: the game in not really girl friendly.
They're not even trying to fix anything. I report a map glitch and after moneths and many patches it still hasn't been fixed.
And what's with that red smoke wave that Siren sends out in KFGame? LoL

After seeing the ignorant replies, I can see why people would be playing KFMod. And I hope this means they stay out of KF Retail.
