Undergrowth

Undergrowth is a region exclusive to the Downpour DLC, with being the only Slugcat that can access it. It is the remains of the Drainage System, now overgrown and a thriving ecosystem. The region is mostly unaffected from the cold in the rest of the world.

Overview
Undergrowth is quite similar in level geometry to Drainage System, with only a few rooms being changed. A lot of the water from Drainage System isn't present anymore. At the far left of the area, a dark mushroom forest can be found, as well as a new  Echo.
