UGNDM KP is a largish death match map for Kingpin. It is a conversion of an unreleased Soldier of Fortune map.
It is a multi levelled map with the lower level being a sewer area. It uses mostly Kingpin standard textures with an emphasis on corrugated metal, has ample weapons and items and 16 player spawns.
Just unzip all the files to your Kingpin folder and they will be placed in the correct locations.
