CRACK game door code: UV Flashlight and all three clue locations

There is no fixed door code

The Redacted keypad needs six digits that change between playthroughs. Dot Esports tested a combination from one run and found it failed in another.

Write down six slots, then fill the positions shown by each UV marking. Finding a pair first does not mean it belongs at the beginning.

Get the UV Flashlight

1. Unlock custom scaffolding through the Work Orders.
2. Bring a Toolbox and Hammer to the ventilation hatch above the Break Room.
3. Build and secure a platform that lets you reach the hatch.
4. Aim at its bolts and use the Hammer’s right-click removal action.
5. Enter the duct and collect the UV Flashlight.

A normal Lantern helps illuminate the duct but does not replace the UV light for this puzzle. Whisper’s door guide also distinguishes opening the vent from tightening scaffold bolts.

All three clue locations

Shine the UV Flashlight on the faint wall markings:

Each location supplies two digits plus their positions. Preserve the blank spaces when recording a partial clue.

The slot-machine room is the expanded Break Room. If it remains locked, complete the Artery Sack assignment first.

If the password is rejected

• Confirm that all six slots are filled.
• Recheck the positions shown by the markings.
• Use the clues from your own playthrough.
• Check the expanded Break Room rather than searching only the original arcade area.

After arranging the digits, return to the keypad and enter them left to right.

What the room unlocks

The room contains terminals, surveillance information, and laboratory records. The Steam player guide describes its computers and Sound Analyser.

This puzzle is separate from the second ending. Opening the room also relates to the hidden Access Granted achievement; details are on the achievements page.
