Drainage System

Drainage System is a water-filled region that consists of a series of indoor rooms, pipes, and tunnels. It is potentially the second region visited in game as or, after , while also being 's starting region. While more difficult than traversing, it serves as an alternative path to or Filtration System due to its compact size.

Overview
Drainage System is a piped network of waterlogged tunnels and large vats of water. Drainage System is entirely underground and contains a large number of flooded rooms. It is accessible early on from Outskirts, but is more difficult to traverse than the intended route through. There are two long one-way drops in the region which funnel the player towards taking the lower, flooded path towards, and make returning to Outskirts difficult.

Some rooms are almost completely flooded with only small pockets of air, and require extended dives to traverse. Certain pools have tidal properties, making them pulsate up and down in height, putting one at risk of drowning or being vulnerable to aquatic predators. This is paired with the difficult to navigate geometry of the region, making the environment a demanding task to traverse.

 * s are more dangerous in water than land, due to their ability to dive.
 * can be temporarily stunned using s. Snails can also stun the player at close proximity.
 * Passing through the lower, flooded section of the map requires extended dives from one pocket of air to the next. When underwater, returning to the previous air pocket to regain breath and try again can be useful if experiencing difficulties passing the terrain smoothly.
 * The water in some rooms in the past lowers and rises. This allows to cross the flooded tunnels, as their breath time would be too low to pass otherwise.
 * s can be used to dive for extended periods of time without resurfacing, when available.

 * Though it's not the only way to circle back to Outskirts, it's possible to travel backwards through Drainage System from the Filtration System gate whilst avoiding the Leech tunnels at the bottom of the region, as demonstrated in the video below.
