A total mish mash of textures and styles. There is no theme except the theme of not having one, and that ain't working either. A heap of custom textures (by Diabolic and Kiltron have been used, abused, stretched and pulled in all the wrong ways. There is a custom teleporter but its missing textures which is a real shame.
The other big problem is the author has included custom shaders and textures with the same names as few included in the id Software .pk3 files. While you have this map in your baseq3 folder, other maps using these textures may not display normally. This is not good.
Gameplay is very dull and bots do play the level but can appear to be lost in the teleporter room.
Best left alone.
