Luigi’s Mansion 3 Walkthrough: Complete Guide & Tips

Introduction

If you’re exploring the haunted halls of the Last Resort on Nintendo Switch, this luigi’s mansion 3 walkthrough is designed to help you enjoy the gameplay, solve puzzles, find hidden rooms, and beat bosses with confidence. Whether you’re new to the Poltergust or an old pro looking for collectible locations and Scarescraper strategies, this guide balances step-by-step tips with big-picture strategy so you can focus on exploration and fun.

Getting started: controls, Poltergust, and Gooigi basics

Before diving into floors and bosses, make sure you have the fundamentals. Understanding controls, the Poltergust G-00, and Gooigi is the foundation of the walkthrough guide.

• Controls: Learn movement, suction, burst, and the dark-light functions early. Precision during puzzles and boss fights matters.
• Poltergust G-00 upgrades: Collect gold and treasure to unlock upgrades. Upgrades affect vacuum power, burst strength, and suction speed—important for both combat and treasure hunting.
• Gooigi: Use Gooigi to reach spikes, vents, and switches. He’s essential for co-op puzzles and many hidden rooms; practice teleporting between Luigi and Gooigi when possible.
• Map and hotel layout: Open the map often to track floors, elevator rooms, and portrait ghosts. Knowing which floors contain key items saves time.

Floor-by-floor walkthrough framework (strategy + examples)

Instead of listing every minor object, this walkthrough focuses on strategy for tackling themed floors, solving puzzles, and locating collectibles like golden gems, statues, and portrait ghosts.

General approach to floors

• Start each floor by sweeping the main lobby for interactive objects and subtle clues.
• Use the dark-light to reveal hidden switches and secret doors; keep an eye out for glints that indicate treasure or gems.
• Use Gooigi to scout tight spots and cross spikes; often a tiny passage hides a golden gem or key.
• When a puzzle blocks progress, look for environmental hints—shadows, paintings, and furniture often tie into the solution.

Example: The Boiler Room (early floor tips)

In many floors with machinery, such as the Boiler Room, steam vents and pressure panels are key puzzles. Tip: disable steam with the Poltergust burst and block vents temporarily with furniture to reach switches. Hidden rooms often sit behind loose brick walls—use the Suction to pull fixtures and reveal breakable walls.

Example: The Garden or Jungle Floor

On flower and plant-themed floors, vines and pots hide keys and golden gems. Use Gooigi to crawl through irrigation pipes and find secret chambers. Many portrait ghosts are concealed beneath foliage—clear dirt piles to find them.

Boss fights and boss guide

Boss encounters in Luigi’s Mansion 3 mix pattern recognition, timing, and environmental interaction. Here are common patterns and specific strategies.

Common boss strategies

• Study attack patterns: Pause and learn the sequence. Most bosses have a vulnerability window after a heavy attack.
• Use the environment: Boss arenas often contain objects you can pull into the Poltergust or smash to create damage opportunities.
• Gooigi support: Gooigi can distract or trigger switches while Luigi attacks the boss. Use co-op or single-player dual-control to your advantage.
• Conserve health: Use healing items only when necessary; some floors have health refills in hidden rooms.

Example boss: The Musician or Phantom-themed boss

These bosses commonly summon minions and create sound-based attacks. Use the dark-light to find glowing instruments or objects they control, stun them with the Poltergust burst, then vacuum them away. When the boss becomes invulnerable, back off and disable the summons or hit environmental switches.

King Boo and final encounters

Late-game bosses, including portrait ghosts and King Boo, require patience. Watch for visual cues that telegraph big moves, target summoned objects that power shields, and prioritize attacks after the boss overextends. Aim for consistent vacuum pulls and timed bursts to create damage windows.

Collectibles, secrets, and Scarescraper explained

Collectibles add replayability. This walkthrough helps you find golden gems, treasure, portrait ghosts, and how to approach the Scarescraper multiplayer mode.

Collectible types and tips

• Golden gems and treasure: Often hidden behind breakable walls or inside packages. Look for subtle color differences and clear piles of debris to expose them.
• Portrait ghosts: Usually tied to mini-puzzles; solving their unique mechanic often grants special rewards.
• Statues and outfits: Some bosses drop outfits or rewards. Complete optional puzzles to unlock costumes that don’t affect gameplay but are fun to collect.

Scarescraper and multiplayer

The Scarescraper adds a competitive and cooperative endgame loop. Play co-op to coordinate where to use Gooigi and to revive teammates. Tip: assign roles—one player scouts and collects, the other handles combat and shields. Communication improves time bonuses and treasure runs.

Puzzles, hidden rooms, and finding every secret

Puzzles range from simple environmental switches to multi-step riddles. Hidden rooms often reward you with needed upgrades or golden gems, so thorough exploration is worth the time.

Tips for solving puzzles

• Observe first: Look for repeating patterns in paintings, floor tiles, or lighting that might indicate a code or sequence.
• Interact with everything: Pull curtains, flip light switches, and vacuum odd objects—many puzzles require interaction to reveal a clue.
• Mix Luigi and Gooigi tactics: Some switches are pressure-based while others are spike-protected; use Gooigi for the latter and Luigi for the former.

Locating hidden rooms

Hidden rooms often have telltale signs: a single tile out of place, a slightly different wall texture, or a faint sparkle. Use the dark-light frequently to reveal transparent walls and activate portrait doors by solving the room’s riddle.

Upgrades, treasure economy, and endgame strategy

Managing your treasure and upgrades affects late-game success. Spend treasure on Poltergust upgrades and health only after securing necessary upgrades that improve your vacuum strength and burst velocity.

Upgrade priority

• Suction power: Helps during boss pulls and when extracting large objects that hide secrets.
• Burst upgrades: More powerful bursts stun enemies and open time-limited windows to reach switches.
• Health and defense: Improve survivability for tough floors and Scarescraper runs.

Money-saving tips

• Explore thoroughly for hidden treasure before buying upgrades—many secret rooms reward enough gold for major improvements.
• Complete portrait ghost challenges early to gain unique rewards that make boss fights easier.
• Replay floors with missed collectibles using the map to track areas you skipped.

Walkthrough tips, pro strategies, and quick reminders

• Always check the map: It flags incomplete floors and secret doors.
• Conserve Gooigi: Avoid using Gooigi in obvious trap zones without scouting first; he can be lost and force a reset of the area.
• Use environmental weapons: Many floors let you use chandeliers, safes, or pianos against ghosts.
• Portrait ghosts hints: They often tie into a theme; think about the room backdrop when solving their puzzles.
• Scare Boo hunting: Boos often hide in drawers and behind curtains. Use the dark-light and listen for whispers to locate them.

FAQ

1. Do I need to play Scarescraper to finish the main story?

No, Scarescraper is optional. The main story and final boss, including King Boo, are accessible without multiplayer. However, Scarescraper is excellent for extra coins, outfits, and cooperative challenges.

2. Where can I find Gooigi most useful?

Gooigi is ideal for traversing spikes, squeezing through vents, and activating pressure switches inaccessible to Luigi. Use him to locate hidden rooms and solve many of the game’s co-op style puzzles.

3. How do I find all portrait ghosts and collectibles?

Thorough exploration, using the dark-light scanner, and revisiting floors after upgrades are the best approaches. Look for subtle environmental clues and use Gooigi to access tight areas where golden gems hide.

4. What’s the best strategy for boss fights?

Learn attack patterns, use the burst to stun, and rely on environmental hazards to break shields. Upgrade suction and burst power early to make boss phases shorter. Patience and timing beat brute force.

5. Any tips for treasure and upgrades economy?

Prioritize Poltergust upgrades that improve suction and burst. Search every hidden room for treasure before purchasing upgrades. Complete portrait ghosts and optional puzzles to unlock extra cash and outfits.
