The Sinking City Side Case And Main Quest Locations

Looking for a specific case location in The Sinking City? We've listed out every single place you can visit in the city of Oakmont!

Openly hostile to outsider newcomers, the city of Oakmont is a confusing maze of flooded streets and back alleys in The Sinking City. Just simply getting around to find locations in any given side case or main quest will often be your biggest hurdle. 

If you can't seem to figure out where to go next, we've got every main quest and side case location in the entire game listed below, broken down by district.

Before we dive in, be sure to check the notes in your casebook before traveling to any of the locations listed below. If the note has a compass symbol in the upper right corner, then you can immediately travel there and access the next section of the case. If the note has a book symbol, however, you need to hit the archives and research the location before any evidence will actually spawn there.

 Letters From Oakmont location symbol

There's one other kink in the format to know about concerning a few side cases.

Unlike other map locations, the Letters From Oakmont and All That Glitters side case locations don't appear on the map after you find them, and they don't give you the normal "key evidence found" or "all evidence found" notifications.

You will know you've found the right place because the compass symbol will disappear from the top right corner of the note in your Casebook, and you get experience for finding the main evidence in that location.

In the case of All That Glitters, the experience is granted after finding a piece of treasure (usually hidden away behind an illusory wall or object). For Letters From Oakmont, the symbol above will also appear in blue while using Mind's Eyes either on the exterior or interior of the building somewhere.

Haven't found how to initiate side cases yet? Here's where and when to grab them:

  • Letters From Oakmont -- from the owner of the Devil's Reef Hotel after finishing the prologue segment in Grimhaven Bay
  • Bounty Of The Sea -- from the man standing under the awning near the Grimhaven Bay fast travel booth 
  • Field Research -- from the doctor at the front desk of the hospital in Coverside
  • Extra Hours -- from the police officer in the Seven Oaks after discovering the Smuggler's Hideout
  • All That Glitters -- initiated by reading a letter on the front desk of the Oakmont Chronicle after being arrested for murder
