A key to the lab

Need a key to get into that hidden lab in The Sinking City 2? Follow this guide to track down Usha and find out how to get to Cthygonnaar.

Alright, so you've been following the trail of Joseph Hill and you've learned about this mysterious Mayan priestess named Usha. She's apparently the one holding the key to getting to Cthygonnaar, and she's been causing a bit of a stir with her vampiric tendencies. Let's figure out how to track her down.

First things first, you'll want to head to the Oakmont Police Department. You need to use their archives to dig up some info on these 'bloodless corpses' that have been reported. Look for a report titled Bloodless corpses. This will give you an address on Old Church Road, between C. Smith Avenue and Maple Lane in eastern Salvation Harbor. That's your next stop.

When you get to the crime scene, you'll find a few Innsmouther corpses and a leather bag. Inside that bag is a Hotel owner's note. After you examine it, you'll trigger a retrocognition sequence. Pay close attention to what you see – it'll point you towards the Devil's Reef Hotel.

At the hotel, chat with the owner. He'll let you search Raymond's room, which is next to yours. Inside, you'll find a few things to inspect, but the most important is Raymond's diary, hidden behind an illusory statue on a desk. This diary is key – it mentions a flooded lab on Moorland Rd, between C. Smith Avenue and Powderhouse Street, marked by five big stones. That's where you're headed next to find the Hidden Lab.
