Subterranean

Subterranean is a late-game region and consists mostly of long dim tunnels filled with dilapidated trains. This is the final region visited when following the intended path as any. The dark pipes of Filtration System connect Subterranean to lower Drainage System and to the caves of the Depths.

Overview
Subterranean spans both sides of the world, connecting to Farm Arrays in the west and Shoreline in the far east. The western side of the region features a steep fissure and a pit overhang, neither of which can be scaled once the player has dropped down. Subterranean is home to a large number of, as well as s that patrol the center of the map. Filtration System also contains a high number of s, which can easily corner and catch the player in dark and narrow crawlspaces. A subterranean lake in the east of the region contains a unique, as well as an albino when playing as. Players with fully upgraded Karma can pass through the Depths.

Filtration System
Filtration System is a dark and dimly lit maze of pipes and shafts connected to Subterranean through four unique tunnels. The lack of illumination makes exploration challenging without a. The subregion is also inhabited by a large number of s, which can easily hunt and corner in narrow crawlspaces. Filtration System can also be accessed directly via Drainage System and serves as the only entrance to the Depths.

Depths
The deepest area in the game, and critical to the plot, the Depths can be accessed through a shaft at the deepest point in Filtration System. There is no threat of Rain, and no natural predators, although the player can be killed if attempting to repeatedly pass the s to the west of the temple compound without the requisite 10th Karma level. There is no simple way to climb back up the entrance shaft. The upper area in the Depths contains a series of temple and shrine-like structures. In order to progress beyond this compound, the player must have unlocked the 10th Karma level, typically acquired by visiting or visiting four. A small room near the entrance of the Depths raises Karma to the current max level. Attempting to make one's way past the Guardians without a maximum karma of 10 will first result in Slugcat being thrown back to the start of the room, and then being flung heavily against the ground after a couple of attempts, resulting in death. Guardians have extremely high health pools and so cannot be killed conventionally.

As the player progresses downwards, the compound gives way to a loose cave system which eventually opens out into a lake of golden dark liquid, known as the Void Sea. Slugcat cannot drown in this liquid, and swimming down into this lake begins the ending sequence.

Trivia

 * There are multiple unintended ways to bypass the Guardians. With good timing it is possible to blind them with two flashbang fruits for long enough to run past. This was specifically patched out for in version 1.5.
 * The Guardians can also be bypassed by distracting them with a living creature. This works best with small living creatures such as Hazers or Vulture Grubs that can be swallowed and regurgitated repeatedly, aggravating the Guardians more quickly.
 * The exit can also be reached by manipulating the Guardians to throw the Slugcat straight upwards, then throwing objects to reach the pipe.
 * It is also possible to fully despawn the Guardians by interrupting their room loading time. This is considered the simplest and fastest method of the Guardian despawn and is used for any% speedruns.

Trivia

 * It is possible to scale the western fissure via a few methods, most commonly s and a or.
 * The western pit can also be scaled with an, or while starving and backflipping with a
 * It is possible, using TAS tools, to return to Filtration System after reaching the Depths.
 * In one of the western entrances to the filtration system, no rain will flood the tunnels, letting the slugcat stay in one area indefinitely.
