Level 4 has the appearance of an empty office building, devoid of furniture except the occasional office water-cooler or abandoned swivel-chair. As well as water fountains, Level 4 also has vending machines containing snack bars and almond water, which makes survival much easier. There are also several colonies of humans living on Level 4. However be warned, many windows on this level are in fact Window entities, (which can be treacherous, although not hostile).
