The Siren's Call Walkthrough

Prerequisites

Reach Devil’s Reef Hotel and collect the Safe Code Letter and “Baby, One More Tide” Lyrics. Room 301 is on the third-floor route behind a cabinet that can be moved away from the door.

Solution

Connect the two records in the Investigation Space. Read the ordered images as four digits: bat wings give 2, a tail gives 1, the eight-limbed beast clue gives 3, and the sins clue gives 7. Enter 2137 at the Room 301 safe.

Outcome and failure states

Opening the safe supplies a pistol attachment and ammunition and closes The Siren’s Call investigation. If the achievement or investigation does not register, confirm the two evidence records are connected rather than entering the code as an isolated shortcut.

This optional safe does not open the hotel basement. For story progression, follow Staff Key → Lorelei Tokens → three triangular keys → Lorelei Lock in the Devil’s Reef guide.
