Escape the Cult: M359, Tongue Key & Leviathan Tip

Leave the chair and open Door M359

At the start of captivity, inspect the restraints and follow the interaction prompts to free Aidan. Look down at his hands and arms rather than at the door. Once free, search the rooms at both ends of the corridor for the Blemished Fragment and Blemished Diamond.

Return to the M359 plaque and use the pieces at the inset. M359 identifies the door; it is not a three-digit password. If the first piece does not finish the interaction, the missing requirement is the other piece. Do not leave the corridor hunting for an unrelated keypad.

Reach the courtyard and the office

The route continues through the lower passages toward the courtyard. Search the room with the clothes and a save mark for the key that opens the next door. Check useful supplies while the room is safe, then use the key across the courtyard.

Beyond this point, observe patrols before moving. Crouching and using cover are more useful than attempting to sprint past every enemy. Work toward the office containing the skull and the face-like door.

Solve the skull and collect the Tongue Key

Orient the skull so that its face points away from you. The sequence documented by PowerPyx is left → back → right → top. The mouth opens and gives you the Tongue Key.

GameSpew describes the side presses from a different viewing orientation. That is why left/right instructions can appear contradictory. Reset the object to the viewpoint stated here before following the sequence. Use the key on the face-like exit, then continue toward Bruno.

Sneak past Bruno and take the keycard

Stay low and follow the outer edge of the room. The keycard is by the occupied table. Wait until Bruno’s attention shifts, take it and return to the card-reader door. Look at the patrol’s current position before each move rather than copying the exact timing of a video.

The painting-hall cabinet beyond this door is optional. Its reported code is 9901, with 0199 also listed by PowerPyx. Read the plaques beside the paintings in your build. The safe and keypad reference separates that cabinet from the later bath-area cabinet.

Reset power in Room 206

After the chase and the early combat rooms, the exit corridor loses power. Take the flashlight near the exit, then find Room 206 and operate its power control. Returning to the exit after that restores the route forward.

The pistol comes on this progression route. Before picking up more supplies, check your carrying space. If a room has both an obvious story item and optional loot, collect the story item deliberately and avoid filling every available slot without a plan.

Use the Leviathan Tip and open the statue

1. Search the security office near the large chapel/statue room.
2. Collect the Leviathan Tip from the desk and inspect the office for its inventory upgrade.
3. Return to the diamond-shaped statue in the earlier art corridor.
4. Place the tip on top, then rotate the three sections until the pattern connects.
5. Take the duck-shaped reward and use it at the matching lock near the security office.

The item’s in-game name is S&M Duckie. It is a physical lock insert, not a numeric code. From here the path climbs toward the club, where the VIP access task is a separate objective interaction. Save before committing to that next stretch.
