The Boiler Room Valve Puzzle

This early-game puzzle requires you to restore pressure to the facility's heating system, located in the dark and grimy Boiler Room on the Lower Maintenance Level.

  1. Locate the Boiler Room Key: Before you can even enter, you'll need the Boiler Room Key. This is typically found in the Janitor's Office, which is accessible from the Main Hallway on the Ground Floor. Look for it hanging on a pegboard near the cleaning supplies.
  2. Access the Boiler Room: Use the Boiler Room Key to unlock the heavy metal door leading into the Boiler Room. Be prepared for low visibility; you might want to equip your Flashlight here.
  3. Identify the Pressure Gauges: Inside, you'll see a large boiler unit with three distinct pressure gauges. Each gauge corresponds to a specific valve. Note their current readings.
  4. Find the Missing Valve Handle: One of the valve stems will be missing its handle. The Rusty Valve Handle is usually located on the floor near a pile of coal in the far corner of the Boiler Room. It can be hard to spot in the dark.
  5. Attach the Handle: Use the Rusty Valve Handle on the unhandled valve stem.
  6. Adjust the Valves: The goal is to get all three pressure gauges into the "green" operating zone. This is often a trial-and-error process, but here's a common sequence:
    • Turn the Left Valve clockwise twice.
    • Turn the Middle Valve counter-clockwise once.
    • Turn the Right Valve clockwise once.

    Hint: Listen for the distinct hiss of steam and the clunk of the gauges as you turn them. If a gauge goes into the red, turn the valve in the opposite direction.

  7. Confirm Pressure Restoration: Once all gauges are in the green, a loud clanking sound will indicate success. The heating system is now operational, and a new path or door will likely become accessible elsewhere in the facility.

The Medical Bay Computer Lock

Gaining access to critical medical records in the Medical Bay requires bypassing a locked computer terminal. This puzzle involves finding a specific access code.

  1. Locate the Locked Terminal: The computer terminal is situated on a desk in the main section of the Medical Bay, usually near the patient beds. Interacting with it will display a "Password Required" prompt.
  2. Search for the Doctor's Notes: The key to this puzzle lies in the personal effects of Dr. Aris, a former resident of the facility. His Personal Logbook is often found in the Staff Quarters, specifically in the desk drawer of the room marked "Dr. Aris."
  3. Decipher the Code: Open the Personal Logbook from your inventory. Within its pages, you'll find various entries. Look for a specific entry that mentions a "birthday" or a "special date" in conjunction with a series of numbers. For example, an entry might read: "My daughter's birthday, 07/12, always brings a smile. She's my little star, 4591." The important part is the numerical sequence.
  4. Input the Password: Return to the Medical Bay computer terminal. Enter the four-digit code you found in the Personal Logbook (e.g., 4591).
  5. Access Granted: If the code is correct, the computer will unlock, granting you access to patient files and potentially revealing crucial lore or objectives.

The Maintenance Shaft Lever Sequence

Deep within the Maintenance Shafts, a series of broken levers controls a heavy blast door. Activating them in the correct order is essential for progression.

  1. Identify the Levers: There are typically four distinct levers, often labeled with faded numbers or symbols (e.g., I, II, III, IV or A, B, C, D). They are usually spread out along a catwalk or within a small control room overlooking the blast door.
  2. Find the Schematic Diagram: A crucial piece of information is the Maintenance Shaft Schematic. This diagram is frequently taped to a dusty workbench in the Workshop, which is usually adjacent to the Maintenance Shaft entrance.
  3. Interpret the Diagram: Examine the Maintenance Shaft Schematic in your inventory. It will show the levers and, most importantly, a sequence of arrows or numbers indicating the correct activation order. For instance, it might show "Lever C -> Lever A -> Lever D -> Lever B."
  4. Repair the Broken Lever (if applicable): Sometimes, one of the levers will be broken. You'll need a Wrench (often found in a toolbox in the Storage Room) and a Spare Lever Handle (which might be in a locker in the Security Office) to repair it before you can proceed. Combine these items in your inventory to create a Repaired Lever, then use it on the broken mechanism.
  5. Activate the Levers in Sequence: Following the order from the Maintenance Shaft Schematic, interact with each lever.
    • For example, if the schematic indicates C-A-D-B:
    • Pull Lever C.
    • Pull Lever A.
    • Pull Lever D.
    • Pull Lever B.

    Note: If you activate a lever out of sequence, the puzzle will reset, and you'll hear a distinct "clunk" sound, indicating failure. You'll need to start the sequence again from the beginning.

  6. Open the Blast Door: Once the correct sequence is entered, the heavy blast door will slowly grind open, allowing you to proceed deeper into the facility.
