It includes the apartment safe code, fuse arrangement, Annex crate, church floodgate code, and optional church puzzle. The full Part One objective continues to the Devil’s Reef Hotel rescue, but detailed steps for the whale, fuel, gasoline, and hotel sections are not established here, so those steps are not guessed.
Before you leave Calvin’s apartment
After the introduction, search the apartment and collect its story notes: “Excerpt From The Dream Realm,” “About The Mask,” “Final Warning!” and “Restricted Section Inventory.” Notes can feed into Investigations; connect related evidence there as you find it, since completed connections can award upgrade points.

Apartment 5 has a safe. Enter 1908—the year shown on the nearby Allen Radio Store sign. You can open it before finding the later note that confirms the combination.
Reach the Miskatonic Library Annex
Get through the first gate
- Leave by the fire escape and take a boat to the closed gate.
- Dock at the jetty, enter the building, and find the first Safe Room. Safe Rooms let you save, store items, and access abilities.
- Read the note in the nearby shop, then find the fuses in the other shop.
- Return to the gate’s fuse box. Connect the blue wires with the straight fuse, the yellow and green wires with the T-shaped fuse, and the red and orange wires with the right-angle fuse.
- Validate the arrangement, then pull the lever to open the gate.
Continue to the Annex
Continue by boat, docking where prompted. When the route forces you through a building during a chase, move through it to reach the next building; a cutscene then begins the Annex section.
Search the Miskatonic Library Annex
Inspect rooms for notes and supplies as you make your way to the Restricted Section. Near a Safe Room, collect the ERC User Manual and Activator Pen, then return to the locked ERC crate. Opening it yields a Voss Compensator, which slows enemies when you land fully focused shots.
In the Restricted Section, take the glowing red ritual book. The route then introduces Corentin and leads toward the church as you pursue the floodgate objective.
Open the church floodgate
Explore the church for items and notes before leaving. It has a Safe Room and a Talent Table, where you can spend Dream Essence on talents. The church’s floodgate code is 1672: the church was founded in 1667, and its bell was made and installed five years later.
Optional church exploration and the Obelisk
For the optional church content, find the Star Key and use it to open the Star Door above the ladder. Take the Trident inside. Collect Night Ore as well; the walkthrough says it can recharge the Nightshade mask for one revive.
Use the “Call Upon Believers” and “First Vision” notes to solve the Obelisk. Set its symbols in this bottom-to-top order:
- Cthylla — Splayed Womb
- Gyrh — Spearhead
- Tsog-Nar — Crooked Cross
- Yig — Serpent Form
Afterward, return the charged Trident to its stand. The optional sequence continues into another dimension, where you can find an altar dagger and face a short boss encounter. Connect the church notes in Investigations for an upgrade point.
Combat and exploration priorities
- Save ammunition. Frogwares describes ammunition as scarce and monsters as tough. The opening route also allows enemies to be avoided in some situations, and defeating them is not generally required for progress.
- Search side rooms. Supplies, ERC crates, shortcuts, and upgrade rewards make exploration useful, even when it is not required to advance the main route.
- Use Safe Rooms deliberately. They provide saving, item storage, and access to abilities or talents, depending on the room.
- Connect evidence. The game’s director says investigations run alongside exploration rather than gating it; optional investigations can yield safer routes, supplies, and upgrades. Frogwares’ design discussion on Xbox Wire describes that approach.
Where this verified route stops
Part One is framed as ending after the rescue at the Devil’s Reef Hotel. Its remaining objectives are to move the whale and obtain fuel and gasoline, then save the woman at the hotel. The available verified steps here do not establish the locations, sequence, or hotel solution for those objectives, so this walkthrough stops at the church rather than inventing directions.
The game is a Lovecraftian survival horror title set in an otherworldly version of 1920s Arkham. For version context, Frogwares Support lists console Patch 1.0.1 for PlayStation 5 and Xbox Series on August 25, 2026, with performance and stability improvements and gameplay and visual fixes. Platform-specific behavior can differ; this route does not rely on a patch-specific mechanic.
