Description
Level -21 appears to take place on a large ship in the ocean. Level -21 consists of randomly arranged corridors leading to empty rooms. There is no light source in these rooms, only hallways. In these rooms you can find many supplies, including almond water, food, weapons, firearms, Wi-Fi, etc. Surprisingly, it is not possible to get to the top of the ship. You can see the infinite ocean only if you look through a window in the corridor. Level -21 has considerable non-Euclidean features, including corridors that cross without intersecting, multiple rooms that occupy the same space, corridors/rooms without floors or panelling, and carpet instead of metal floors.
Control Rooms
A control room can be accessed by opening doors. A captain can be found in the control room. The captain is a Facelings, who appears to be a tall man in his 40s, dressed in a dark blue captain's uniform. He is friendly unless you try to kill him also dont try to kill him with pryoil, it wont end well.
Cafeteria
There is a cafeteria in this level that has most of the foods in existence, which also refills every so often, being the best source of food in this level. There are many passive Facelings in here.
Glitches
Corridors and rooms are sometimes subject to what settlers often call glitches, which are periods where the floor and walls may fluctuate in their material composition. Examples of these anomalies might swap a mental floor with an assortment of uncovered wooden beams, or metal grating. Standard drywall halls may dissolve into bathroom tiles or sheet metal tunnels in patches and unstable grids. The nature, cause, and immediate effects of these anomalies are yet to be determined, although they have been deemed as minor inconveniences and not much else. In areas where an anomaly has deteriorated the components of the level, settlers are advised to avoid and instead travel through more stable locations. Over time these affected areas will revert to their original state with no apparent residual effects.
