Description
Level 133 is an futuristic military facility. The facility of level 133 consist of hallways, infirmaries, chemical labs and armories.
Hallways
The halls of level 133 are similar to the hallways of any building with the exception of mechanical whirring and human shouting echoing through the halls. To enter another room from the hall, a wanderer must press their hand on a door with the name of a room listed above. If done correctly, they will no-clip through the floor and into the selected room however wanderers have occasionally came across fully black walls which will no-clip the wanderer into a random room of the level.
Infirmaries
The Infirmaries of level 133 are where most of the supplies are located on this level. The supplies contained within level 133 are Almond Water and Royal Rations. The supplies restock on a regular basis but are known to also "spawn" entities during a restock.
Due to the hostile factions and the spawning of entities, the Infirmaries are high-risk, high-reward.
Chemical labs
The chemical labs have the appearance of a standard chemistry lab full of mixing machines where different substances such as Almond Water Liquid Pain and Cashew Water can be found inside of beakers and flasks. While these substances behave like normal, when combined using the mixing machines, they form a substance that is known to damage human organs and entities alike. It is advised to stay away from chemical labs as the substances made in the labs can be very harmful and hostile factions tend to stay around these areas collecting the substance, making these rooms very dangerous.
Armories
The Armories contain different weapons and ammunition that can be used to a wanderers' advantage. The Armories are the most dangerous due to hostile factions using the room for restocking weapons. Similar to the Infirmaries, the Armories create a high-risk, high-reward situation.

Hostile factions
The term hostile factions refers to factions of any size on both sides of the conflict. These factions are to be avoided due to their undocumented nature.
The conflict
The U.E.C discovered level 133 on February, 30, 1942 and has since been used to supply weapons and supplies. This caused the Eyes of Argos to invade the level in order to "purge the sin of ground 133". Since then, many different factions have showed up for their own reasons.
Entrances and Exits
The only entrance to level 133 is from Level 127 through metallic doors and a wanderer can exit from the same way the wanderer came from.
