Hello Tripwire, I'm Asi. I currently own a game of you'res by the name "Killing Floor" It is a wonderful game and has brought me days of enjoyment. I've noticed though that you're game is somewhat bugged with the whitelist system. Some maps and even mutators that come preinstalled with the game Won't work, Or have been blocked for no reason what so ever. The whitelist system was put in to keep people from using custom maps to level there perks, The way your using it though its getting in the way of players. For example the map "Farm" and the mutator "bloat-ed" will not go together, when the perks are checked from the main menu a "Unknown steam error" comes up. The whitelist system has done more harm then good, By signing this petition you are requesting that they remove the whitelist system for mutators and maps that come with the game. Thank you for you're time.
