Welcome to the ultimate challenge in the 3DS remake of a classic: my complete 100% walkthrough of Luigi's Mansion (2018) on Hidden Mansion Mode! If you thought the main game was spooky, prepare for a true test of your ghost-busting skills in this unlocked, harder difficulty. Join Luigi as he bravely (or not-so-bravely) re-explores the haunted mansion, facing stronger ghosts, less health, and trickier encounters. This guide is designed to help you conquer every aspect of this demanding alternate play through, all captured in crisp 1080p and a smooth 30 frames per second. 00:00:00 - Intro 00:01:32 - Area 1 00:09:23 - Neville (Study) 00:10:58 - Lydia (Master Bedroom) 00:12:39 - Area Boss: Chauncey (Nursery) 00:19:30 - Area 2 00:22:24 - The Floating Whirlindas (Ball Room) 00:40:51 - Shivers (Hallway & Butler's Room) 00:46:07 - Melody Pianissima (Conservatory) 00:49:24 - Mr. Luggs (Dining Room) 01:00:00 - Spooky (Boneyard) 01:01:36 - Area Boss: Bogmire (Graveyard) 01:07:11 - Area 3 01:11:56 - Biff Atlas (Rec Room) 01:20:08 - Nana (Nana's Room) 01:22:46 - Miss Petunia (Bathroom) 01:32:42 - Slim Bankshot (Billiards Room) 01:35:02 - Henry and Orville (The Twins' Room) 01:39:07 - Madame Clairvoya (Fortune-Teller's Room) 01:52:48 - Area Boss: Boolossus (Balcony) 01:57:48 - Area 4 02:08:44 - Boss: Uncle Grimmly (Wardrobe Room) 02:15:28 - Boss: Clockwork Soldiers (Clockwork Room) 02:28:06 - Boss: Jarvis (Ceramics Studio) 02:40:21 - Boss: Sir Weston (Cold Storage) 02:49:40 - Boss: Sue Pea (Guest Room) 02:53:01 - Boss: Van Gore (The Artist's Studio) 03:01:12 - Final Boss: Bowser and King Boo #LuigisMansion3DS #HiddenMansion #LuigisMansion #Nintendo3DS #Walkthrough #100Percent #GamingGuide #Nintendo #LuigiRemake
