The MAC 10 recently introduced in the 1014 update for Killing Floor seems to have caused some confusion due to a never released weapon created by a community member named Ricardo.
The gun in game is not his. If it was, his name would be highlighted in the patch notes. The weapon in game was created by one of our on site artists who made it in his spare time. He has other weapons as well he's made that I am trying to work out of him but that is a different story
Now back to community made items. This is something I would really like to support going forward with the Tripwire team having the majority of their time occupied on RO 2. To that end, if anybody creates a weapon or character or zed that is up to the quality of the stock game, we would gladly introduce it as stock content.
We are also thinking of ways to promote the creation of said content, but do not have anything to say on this yet.
