Based on an Italian palazzo, the map has a very simple layout. Two story building with a stairway between levels, central courtyard, lots of pillars and many doors to very similar rooms.
Most items are placed within these closed off rooms and since they all look the same, its hard to build a mental map of where everything is. With flat exterior lighting the level looks more like a 3D architectural model than anything else.
With so many doors, the constant sound of opening and closing gets real annoying and its always a dead give away where your opponent is. Bots navigate the whole level fine.
