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 Outskirts

Overview
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 Industrial Complex. There are two long one-way drops in the region which funnel the player towards taking the lower, flooded path towards Garbage Wastes, and make returning to Outskirts difficult. Some rooms are almost completely flooded with only small pockets of air, and require extended dives to traverse.

Tips

 * s are dangerous in the water than land, due to their swim speed.
 * 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.
 * s can be used to dive for extended periods of time without resurfacing, when available.
 * Reaching the Outskirts gate from the Filtration System gate is possible by using multiple spears to climb the side of a tall vertical shaft.
