Hi this is practically the best way i level up'd my stats to perk level 6 for kf v 1058. this was only tested on my cracked version of the game not my steam original version as i don't want to get banned so haven't tried.
1. download the file from below
2. extract it to your killingfloor root folder
3. start the game or restart the game (as admin if necessary)
a screen shot is also applied
and there you have it.
