The Room 301 Safe in The Sinking City 2 can be opened with the code 2137. The clues are found inside Devil’s Reef Hotel and point to the numbers 2, 1, 3, and 7.

Where to Find the Room 301 Safe

The Room 301 Safe is located on the third floor of Devil’s Reef Hotel during Chapter 2: The Wake-Up Call.

Once you reach the third floor, head toward Room 301. A cabinet blocks the entrance; push it aside to access the room. The safe is sitting inside, but you'll need the correct four-digit combination to open it.

You can technically enter the solution immediately if you already know the code, but The Sinking City 2 provides clues that let you work it out yourself.

How to Find the Room 301 Safe Clues

The combination is revealed through two pieces of evidence found inside Devil’s Reef Hotel: Safe Code Letter and Baby, One More Tide.

The lyrics contain four important references. Each one represents a number:

Bat wings - 2
Tail - 1
Octopus hearts - 3
Sins - 7

Putting those numbers together gives you the four-digit combination 2137. The octopus clue is particularly easy to misread, since the note intentionally points you toward its three hearts rather than its eight arms.

Room 301 Safe Code Solution

Once you've found the safe in Room 301, interact with it to bring up the combination dial.

Room 301 Safe Rewards

Opening the safe rewards you with Voss's Aiming Grip, a pistol attachment that adds a timing marker to your crosshair. Landing shots at the correct time allows you to deal increased damage.

You'll also receive ammunition from the safe, making this optional puzzle worth completing while exploring Devil’s Reef Hotel.
