Metropolis

Metropolis is a late-game region exclusive to the Downpour DLC, with being the only Slugcat that can access it.

Overview
Metropolis is an Ancient city built on top of ' superstructure. After the Ancients ascended, the city became abandoned and derelict, with wildlife like the Scavengers settling in it. The entrance to the city through its Karma gate is restricted to citizens, requiring an identification drone to enter through it. Because of this, the Artificer is the only Slugcat that can enter Metropolis thanks to her drone, Sofanthiel.
