What started as a piece of fan art which by it's own merit gained it's own fans the creator, Hipnox, decided to take it further. The plan is to make a brand new zed for Killing Floor, a female flesh pound, who is not only aesthetically different but has it's own behavioural functions to set it apart from her male counterpart. Thus, the fan art became concept art and in time a full 3D model had been made and textured. Now all that is left is the animations and implementation.
