An unhappy choice of textures, any of which would have been interesting as a feature but looking shocking bad used all together. The same four main textures are used right across the whole level and the result is most underwhelming. The architecture is also very basic with minimal detailing. So clearly texturing and architecture are not the focus of this level. The gameplay on the other hand is good, for a tourney 1on1 match. Although you can dominate the map from the top, and the item placement concentrates play on the bottom level. No rail gun. Bots are just too easy on this map.
A re-texture could improve the aesthetics, but only good against humans.
