Cramped halls and poorly placed escaped routes lead to more aggravation. And poorly molded walls make it seem like it was cement painted like a mountain. No effort went into creating the illusion of rock. Game play, here it is. You can hardly defend your base strategically unless you are a camping demo man or a sniper covering the way to your base.
Engineers can have a hay day because of the cramped areas and ledges for their man melters.
Poor flag placement, falling of ledges. Poor placement of battlements, which also means capture point. Good speeds throughout, but cramped situations make it hard to attack or defend. I personally didn't like this map too much. I think a little bit more planning would make it far better to play in.
