Basement - E. Gadd Walkthrough

Luigi's Mansion 3 guide hub

Escape the hotel’s opening trap, recover the Poltergust G-00 and rescue Professor E. Gadd. This opening route also visits the Grand Lobby and the western Mezzanine before the basement becomes your base.

Escape Room 503

Explore the hotel before going to bed. After the nightmare begins, follow Polterpup through the corridors and escape King Boo through the laundry chute. In the basement, follow the dog into the garage. Search the car to recover the Poltergust G-00.

Learn the Poltergust

Use suction to remove cloth and loose objects, blow to move mechanisms and Burst to knock back close enemies. Flash a ghost with the Strobulb, vacuum its tail and pull in the opposite direction. Slam it once the meter fills; using the captured ghost to hit others makes group fights shorter.

Reach the second floor

Take the service stairs up to the Grand Lobby. Clear the reception ghosts and search the desk area for the key. Follow the accessible upper corridor to 2F. Use the room keys and Strobulb sensors to progress; the Suction Shot is introduced after establishing E. Gadd’s laboratory.

Recover the Dark-Light

Follow the rooms toward the storage area and retrieve the Dark-Light Device. Use it on missing furniture and ghostly paintings, then vacuum the released spirit balls to finish restoring an object. Return to E. Gadd’s painting and shine the beam on it to free him.

Steward — basement boss

Bring E. Gadd down to the garage. Steward blocks flashes with luggage. Vacuum the luggage away, flash him when his face is exposed and capture him. Collect the elevator buttons and let E. Gadd set up the laboratory.

Laboratory and next objective

Use the lab to check ghosts, gems and achievements. E. Gadd sends Luigi to 5F for his briefcase. Several basement and lobby gems require Gooigi, so return after completing that errand. Do not spend time trying to pass the fenced garage as Luigi.

Gems and floor completion

Use the six-colour list to finish this floor. Check the required return visit before trying a route that needs Gooigi, Super Suction or the later Toad mission.
