The map is split into 4 distinct levels, a basement, ground floor an upper floor and 2 sniper balconies. each level offers different amounts of exposure and different route options. There are simple routes, and a number of more difficult paths in the main room for those skilled at double jumping or rocket jumping. The crowning feature of the map, and the source of it's name is the reinforced glass doors that cover the floor of the middle area, and the front end of the team bases, letting you have a glimpse of what is going on in the floor below.
