Exploring the spooky corridors of Luigi's Mansion 3 requires a sharp eye, especially when attempting to collect every hidden treasure. The Boilerworks floor, also known as floor B2, contains six elusive gems that test your puzzle-solving skills and mastery over Gooigi. Tracking down these specific collectibles requires manipulating water valves, dodging mechanical hazards, and finding hidden pipes beneath the sewers.
Navigating the Main Sewer and Valve Puzzles
The first set of challenges on floor B2 involves altering water levels to reach submerged areas. Players must utilize Luigi's vacuum to rotate massive wheels that redirect the flow of dangerous liquids. Coordinated actions between Luigi and his gooey counterpart ensure you can cross previously inaccessible channels safely.
One specific gem requires sending Gooigi through a green pipe located behind a metal panel near the flooded rooms. Before he can reach the prize, Luigi must locate a hidden valve under the floorboards to stop a continuous leak. Utilizing the dark-light device reveals the missing floor grates needed to complete this intricate operation.
Surviving the Mechanical Hazards and Shark Encounters
The lower levels of the Boilerworks present several unique combat and movement hurdles that can catch players off guard. Hidden ghosts and aggressive aquatic threats patrol the narrow walkways, forcing you to use your Strobulb flash effectively. Maintaining a safe distance from these hazards allows you to safely analyze the environment for hidden mechanisms.
When encountering the ghostly shark threat in the basement level, strategic positioning is the absolute key to survival. Experienced players recommend utilizing the small buoy structures scattered in the water to create a safe barrier between Luigi and the enemy. Reaching the nearby ladder quickly or activating a well-timed explosive trap will permanently clear the path forward.
Activating the Central Boiler Control Systems
Unlocking the final rewards on this floor requires successfully powering up the primary control panel in the central machinery room. This complex room features three green steam tanks equipped with red valves alongside several rotatable pipes. Managing the directional flow of high-pressure steam allows you to safely navigate the upper scaffolding.
To start the sequence, players need to turn the green tank opposite the main stairs to initiate the machinery. Redirecting the red pipes activates a conveyor belt, which must be carefully timed to open up further paths. Once the steam reaches the upper control console, pressing the main button unlocks the remaining gates guarding the final collectibles.
