Where to Find the Sun Quartz Puzzle Box
The puzzle box is in the Lead Researcher’s Office, East Wing 2F. The office door is locked with a padlock that must be melted using the Corrosive item.
What You Need Before Starting
The Corrosive is in a cabinet in the Conference Room, also on the East Wing 2F. The room is accessible once you have the East Wing 2F access from story progression. Pick up the Corrosive before heading to the Lead Researcher’s Office.
Important: the Corrosive is a single-use item. Use it only on the Sun Quartz Box padlock.
Exact Solution
Use the Corrosive on the padlock to open the office. Inside, examine the photos and documents on the wall to find the symbol sequence. The correct input is:
- Star
- Sun
- Moon
- Sun
After entering the sequence, the box opens and gives you the Sun Quartz and the Leatherbound Notebook.
Why This Code Works
The wall photos and documents in the Lead Researcher’s Office show the research timeline in symbol form. The sequence mirrors the order the symbols appear across the clue photos — that is the in-game logic the puzzle checks, so you can verify it yourself instead of trusting a guide.
What You Get
- Sun Quartz: the second of the three Quartz pieces needed for the Central Hall mechanism.
- Leatherbound Notebook: contains research lore and a document that helps you open the Organ Transport Box later.
What To Do Next
After collecting the Sun Quartz, your next target is the Star Quartz: get the Level 2 ID Wristband from the corpse in the East Wing Examination Room to open the Isolation Ward, then take the Level 3 ID Wristband from the Security Manager’s body in his office — Level 3 opens Emily’s cell, and only Emily can read the Braille code on the Star Quartz Box. Once all three Quartz pieces are collected, see the Central Hall Quartz Mechanism to open the path to the Courtyard.
Common Mistakes
- Using the Corrosive on a door other than the Sun Quartz Box padlock — it is single-use.
- Missing the Leatherbound Notebook on the desk next to the box.
- Forgetting the symbol sequence after reading the wall photos — the code is also listed in the Quick Answer at the top of this page.
