Big, bold architecture, nice use of Pete Parisi's BadMeat textures without being over the top and good details. This maps gets off to a good start. The layout is not too complex and fairly well connected but some parts of the level do not see much action, even in a six player FFA. The focus of the level is the Quad/RL/SG room with many exchanges taking place across the valley. Small detours to the 100Health, RG or Red Armour will lead you back to the action. A small nit-pick is that the entire level seems like it has been scaled up 50%. Game play is enjoyable with 4-6 players. Bots play ok but do not stray for the RG or Quad. As a bonus, there are two music packs available with an industrial/metal flavour. Download the Bryan version (~14 meg) or the Deiru version (~8.5 meg) and enjoy.
Well worth a few rounds and may stay around even longer.
