An arena style tech base with a nice use of rocks to define the perimeter and exterior areas. This is a very cool DM map with great gameflow. The niggling points are the lack of clip brushes around the rocks and the overall darkness of the map. Its only a touch too dark and the dimness certainly adds to the atmosphere but it has a small negative impact on the gameplay.
Well worth the download, just don't go looking for the errors like me :]
