Survivors in the Fog

Exploration Stage: Foggy Backstreet
From: Mr. Black
Description: We managed to find out that someone left Carlos messages throughout the Foggy Backstreet. Let's look into every cache we can find - what if Carlos forgot to cover his tracks? Check out that forged ventilation grate, it's easy to hide something behind it.
Completed: Ha, I was right! Behind the ventilation grate, there was a message on crystal chip paper: "We're alive! The scavengers taught us how to survive in the fog." Hmm, the handwriting is the same as the Comet's note, which Rayden found in Carlos's workshop.
