The textures and models in this map differs a lot from what is usually released. They are all good looking. The problem with this map is that it has poor gameplay. The different tasks you have to do spawn a heap of monsters that takes quite a while to defeat. Then you're off to the next place for the same thing. It doesn't require any co-operation either. I wish the mapper would have chosen to make the map something other than a simple walkthrough. A defense map would have been excellent in this environment.
Watch out for the zombies, they are suprisingly lethal.
