Tripwire Interactive announces they have launched a Steam Workshop for Killing Floor, their co-op survival/horror shooter. Word is: "For the players, this means that you can find new content for your favorite Tripwire Interactive titles on the Steam Workshop. You will find a ton of community-made maps, mutators and mods of all kinds in there. More importantly, you can subscribe to content you like and be sure that you will always have the latest version as Steam Workshop will automatically download it for you and update it whenever the creator puts a new version in the Workshop." To celebrate, the Tripwire Interactive Bundle on Steam is on sale for 66% off.
