Keys and Progression Items

This checklist tracks objects that open or power the main route. It is not a 100% collectible list.

Early underground

• Rusty Spoon: picked up early; clears marked rubble and pests.
• Lever handles / key items: collect highlighted mechanical parts and return them to nearby inactive levers or locked gates. The exact display names vary by pickup; follow the matching environment rather than carrying them past the next signed route.

Storage and Surface facility

• Foreman’s Key: a launch-day player independently identifies a door opened by this key and reports sheet music behind it. The complete key-chain order still needs direct reproduction, so use the facility signs to locate the matching branch.
• Uncharged Capacitor: recovered before the charge-station sequence. Bring it to the Battery Charge Station only after resetting the signal equipment.
• Charged power item: retrieve the capacitor after charging and install it in the downstream power panel to open the route onward.

Late route

• Nursery Key: opens the Nursery and Julian objective chain.
• Missing blanket/objective item: found in the connected late-game route and returned to advance Julian’s sequence.
• Lantern: obtained after the symbolic Merkert sequence; press F to toggle it and use it through the remaining red tunnels.

Pick up highlighted side-room objects when convenient, but do not assume every painting, toy or sheet is required for story completion. The all-collectibles route remains under verification.
