Core City Sewers form a large part of Core City's lowest level, the docks.


The sewers of Core City. The tunnels travel everywhere under the city, and contain many routes to other areas. Some muties also live down there.

The hiding place of Cornell's gang, Acid Hunters, is hidden in the deepest part of the sewers in northwest, under a large drain pipe. It can be found only after you gain information on it from one of Core City's oligarchs.

The eastern part of the sewers becomes accessible after completing any of the three oligarch's questlines. However, the sewers and connected areas cannot be explored entirely in a single playthrough:

  • Coretech questline leads you to Zaman's Lair, but it can visited at any time without working for Coretech.
  • During JKK questline, the route leading to caves (Core City Underground) becomes accessible. It leads to the back entrance of Coretech warehouse on Core City's lower level. This route also becomes unlocked after the warehouse events of other Core City oligarch questlines.
  • During Praetorian Security questline, The north and northeast areas of the sewers become accessible once you get the Sewer Gate Key. In addition to a broken power generator and the devil rathound Jookhela, the area contains Mysterious Pillars similar to the ones found in Silent Isle.
