Probably going to be my only town map.  This map has an underground sewer and 3 levels of building to go on.  Sewer, ground level, second floor, and rooftops.  Everything is spaced out so it is hard to kill yourself by falling.  Most falls will not even hurt, which makes for quick movement around the map.  This map is one of my favorite run and gun maps, but can be very good for sniping too.
