Level 15 consists of an extensive set of hallways with futuristic-esque architecture and technology, spanning an estimated 700,000 square miles. Periodically, lights in certain hallways will deactivate, creating pitch-black areas. Much of Level 15 has constant sounds of machinery/mechanical whirring. The origin of these sounds cannot be placed. Additionally, most hallways in this level have rooms with unknown machinery resembling control panels. The controls on these machines do not appear to serve any purpose, nor function at all.
Level 15 is split into two sectors: 1st Class, and the Lobby. 1st Class is the first sector one will encounter upon entering this level. It consists of the futuristic halls and technology previously mentioned. Rarely, entities can be spotted in this area. The Lobby is the second sector one may come across after wandering far enough in the first area. Entities are more common in this sector, however most are docile. Rooms are more common in this area, with the addition of cameras on the ceiling. Pieces of furniture can also be found, such as chairs and small tables. This sector has a main area, similar to a lobby, that has a computer. This computer has access to most of the cameras in the surrounding area. It is unknown whether there are more lobbies or computers in this level, as it has proven difficult to navigate, or even enter.
