Core City Underground is a natural cave area accessible from west Core City Sewers after the warehouse events in Core City.

Description

First area of the caves has some pipeworks leaking green mutagen and shacks inhabited by Mutants, just like the ones encountered in Depot A. Going deeper east into the caves leads into a large cave filled with spiderwebs and Coil Spiders waiting for prey to walk into their webs. Deepest part of the cave ends in the lower level of Coretech's warehouse, just below Core City's lower level.
