FAR: Changing Tides Underwater Guide | Circular Door, Windy Chains, and Boost

Lower the winch, attach the hook to the blue fastening underwater left, and pull the metal. Follow the new left passage down and right, then use the upper blue handle to open the door back to the ship.

Detach the hook and connect it to the capsule beyond the new door, then lift it. The blue button in the hole beneath opens the circular door.

Bring the ship to the half-sunken train and use the mast and upper ladder to reach the chains. Strong wind appears as thick white lines; weak wind as thin lines. Hold blue handles during strong gusts, then advance as soon as they weaken. Waiting for no wind leaves insufficient movement time.

Transport fuel with the facility's bottom hook, then use the box to reach the upper furnace. Keep its gauge blue and cool overheating with the hose to extend the blue boost line. When the button protrudes, press it, then release the core with the upper button.

1. Lower the small rooftop winch and take the core.
2. Winch it upward and use the bellows to move the small machine to the far left.
3. Lower the core to the ship and install it.
4. Run the ship's furnace, then use boost after cooling and charging.
