Where to Find It
Chapter
The Sewer
Location
Sewer maintenance area — a keycode door beside a wall map showing the two code halves.
Step-by-Step
- Find the first half: facing the fleshy wall in the maintenance area, look behind the shelf to the left — the wall shows “58**”.
- Find the second half: in the corridor with the second hanging cyst, a 4-digit code on the wall reads “**61” (first two digits rubbed off).
- The map beside the keycode door confirms the two halves combine in order.
- Enter 5861 on the panel. Inside: two handgun bullets, a fleshy wall reach (son's family drawing), and the What's in the Hole? + In Good Hands achievements.
What It Unlocks
The code-door room with the son's family drawing collectible.
