About the only negative thing I can say about the level is that the nuclear strike bug still exists. It's a small complaint, and other than that I truly love the map. The scale is odd, the rooms are connected, but for no apparent reasons. The area opposite the bunker is a perfect maze of buildings, ramps, and stairways. The weapon placement is perfect.
Connectivity is fluid and never slows down.
The bunker itself is an amazing feature. The gun turrets are perfectly placed and are bueatifuly crafted. The only con was that it is a little large, but that can be good for team games. This is my new addiction, Valve has once again convinced me that Half-Life is the best game of the year. They are both good.
