Milk Run: Aftermath - Milk Run: Search and Rescue
The Underground is located at the bottom of the crater and home to a growing population of Necrosi and a fledgling crime syndicate. This tier is policed by GEN Security Officers Level 0 and are considered by the Necrosi citizens as being nothing more than gang members who want to order people around. The Necrosi very rarely leave this tier unless they happen to be Guardian Enterprises employees, or want to leave the city for whatever reason. Several Necrotic Augmentation centers happen to operate in this tier.
