The credit goes to David Hayward, the original author of Alien Swarm UT2K4 mod. I borrowed most of the files from that mod. The reason for the large size map, 51MB. This map is for Killing Floor 2.50-2.
The map is to be played for Killing Floor 2.50-2. The map is a conversion form Alien Swarm, an Unreal Tournament 2004. The map size is large so it might take a while to download it. 51MB. NOTE: Please read this important message - Dottie33.freewebpages.org.
