Luigi’s Mansion 2 walkthrough: full guide to every mission, boss, and gem
A reliable Luigi’s Mansion 2 walkthrough has to do more than tell you where to go. The game is built around short, tightly designed missions inside haunted mansions and outdoor locations, and the moment a player runs out of capture stamina, gets lost in a dark corridor, or misses a hidden Boo, the experience slows down. E. Gadd sends Luigi to Evershade Valley to recover the shattered Dark Moon, and each of the five mansions that open along the way has its own visual identity, ghost roster, and puzzle rhythm. The walkthrough below treats every mission as its own self-contained design problem: where to enter, what to scan, which ghosts are safe to fight first, and which rewards are worth going back for after the credits roll.
What follows is a mission-by-mission reference for both the original 3DS release and the HD remaster available on modern platforms. Boss strategies, gem locations, and Boo hunting are organized per mansion so that the page can be read in order or used as a targeted lookup. Where the two versions differ, the change is called out explicitly. The goal is the same one Luigi has in the game: clear every room, recover every shard, and finish the job without losing all of his health to a single surprise ambush.
Core systems you need to understand before any mission
Luigi’s Mansion 2 looks like an action game, but the moment-to-moment play is closer to a survival horror resource loop. Three systems drive almost every decision in any Luigi’s Mansion 2 walkthrough: the way the Poltergust 5000 captures ghosts, the way light reveals secrets, and the way the mission timer and rank gate your progress.
Light, the Dark Moon, and why it matters
The Dark Moon hangs above Evershade Valley, and every ghost in the game is calmed by its glow. At the start of Luigi’s Mansion 2, the Dark Moon shatters, the valley darkens, and the ghosts go feral. Every mission Luigi accepts is one of the recovery missions E. Gadd assigns to put a shard back in place. The visual changes as shards are restored, and the ghost AI in the affected mansion also calms down, which is why some late-game mansions are noticeably easier than the early ones if you arrive with most shards in place.
How the Poltergust 5000 actually works
The Poltergust 5000 is Luigi’s primary tool, and the way it functions drives most combat puzzles. The flashlight stuns ghosts when you hold the beam steady over them. Once stunned, you press and hold the capture button to suck the ghost in, then tug in the opposite direction when the ghost struggles to deal damage. The number on the top screen counts down from 100 to zero, and at zero the ghost is captured. A bigger number, like the red health bar of a boss, means you need more cycles of stun, capture, and tug.
Two upgrades change the rhythm of every fight. The Poltergust upgrades, earned by completing the upgrade sequence inside the first mansion, raise the capture speed and add the ability to interact with possessed objects. The Dark-Light Device, a small projector you pick up later, reveals hidden Boos, invisible items, and faint graffiti. Any Luigi’s Mansion 2 walkthrough that ignores these tools is leaving a lot of captures and gems on the table.
Stamina, hearts, and the mission timer
Luigi starts each mission with a fixed amount of health and a mission timer. Taking damage removes hearts, and falling into a pit or being hit while already low ends the mission. The mission timer is not just cosmetic. Reaching the exit before the clock runs out determines the rank you receive, and a higher rank unlocks the harder versions of the mansions in the post-game. If the timer is low, the smarter play is to sprint for the exit rather than chase a final Boo.
The Dark-Light Device and Boo hunting
Each mansion has a fixed number of Boos that the Dark-Light Device reveals as faint outlines. Capturing all Boos in a mansion unlocks the corresponding gold paint job for Luigi’s flashlight, and the game tracks the Boo count per mansion in the lab. Most Boos appear only when the Dark-Light is shining on the right surface, so if a hallway feels too clean, sweep the walls, the floor, and the ceiling before you leave.
Controls, upgrades, and loadout decisions
Because Luigi’s Mansion 2 was designed for the 3DS, the controls have been remapped in the HD remaster, but the underlying actions are identical. Knowing which actions exist and when to use them is what separates a quick first clear from a long, frustrating one.
Action reference and what it does
- Flashlight (left trigger / ZL on Switch): Stuns ghosts in the beam. Holding it longer keeps the stun going, so a steady hand on a green ghost in a wide room is safer than a quick flick.
- Capture (right trigger / ZR on Switch): Activates the vacuum once a ghost is stunned. Hold to pull, release to reset, repeat.
- Stun tug: When the capture meter spikes, drag the analog stick in the opposite direction the ghost is pulling. This is the damage step of every cycle.
- Burst: A short stroboscopic flash that pushes a group of ghosts back. Useful when two or three green ghosts corner you, less useful against a single big target.
- Suction shot: Pulls interactive objects from across a room. Required for ropes, curtains, and a few light chains used to expose hidden gems.
- Dark-Light Device (directional): Reveals hidden Boos, wall messages, and a few invisible switches. Always carry it once you have it.
Upgrade path and what each upgrade unlocks
The Poltergust 5000 receives upgrades in a fixed order across the campaign. Skipping an upgrade mission locks the next one out, so even players who just want the Luigi’s Mansion 2 walkthrough boss order should plan to clear every upgrade step.
| Upgrade | How to unlock | Effect on gameplay |
|---|---|---|
| Poltergust 5000 capture upgrade | Complete the upgrade sequence in the first mansion (Gloomy Manor) | Faster capture bar, opening combat to larger green ghosts earlier |
| Dark-Light Device | Awarded after a specific mid-game mission | Reveals Boos and wall messages; required for hidden gems |
| Suction shot / object pull | Granted after a separate upgrade mission | Allows Luigi to grab objects from a distance for puzzles and light exposure |
| Improved flashlight | Final upgrade tied to late-game progression | Wider, brighter beam, shortening the time needed to stun roomfuls of ghosts |
Most of these upgrades are gated by short side rooms, not by story progress. A Luigi’s Mansion 2 walkthrough that lists only the boss path will miss a few of them and make later fights much harder than they need to be.
Pre-mission checklist for any mansion
Before you step through the door of any of the five main mansions, the lab gives Luigi a short briefing. A few minutes of preparation here saves real time in the mansion itself.
- Check heart supply: E. Gadd restocks the Poltergust with hearts, but only up to a fixed maximum. Confirm you are not walking in with one heart and a long mission ahead.
- Confirm Dark-Light Device is charged: The device is recharged between missions, so it should always be full, but it is worth a glance before a Boo-heavy mission.
- Read the briefing card: Each card lists the target shard, the suggested approach, and the kind of ghosts that appear. The card also lists the mission timer.
- Plan the route by elevator stops: Most mansions have an elevator with at least two floors, and many have a basement. Knowing which floor the shard is on helps you decide whether to take the elevator up first or sweep the ground floor for Boos and gems.
Gloomy Manor: walkthrough for all missions
Gloomy Manor is the tutorial mansion in disguise. It introduces the light-and-darkness combat loop, the Poltergust capture cycle, and the elevator system that every other mansion will reuse. The first mission also serves as the Luigi’s Mansion 2 walkthrough intro and is gentle enough that mistakes are not punished too harshly.
Mission A-1: A Painful Night
This mission is designed to teach the capture cycle without overwhelming Luigi. The first green ghost appears in the entrance hall and is easy to isolate. The right approach is to walk slowly into the beam and let the ghost’s heart appear, then stun, capture, and tug once or twice. By the end of the mission, the player should be able to clear a single room of two or three ghosts in one careful pass.
Mission A-2: Poltergust upgrade sequence
The Poltergust upgrade mission doubles as the moment Luigi gains the ability to interact with curtains and small furniture. The room the upgrade is hidden in is reached by interacting with a painting on the upper floor. The Luigi’s Mansion 2 walkthrough for this mission is short on combat and long on hidden switches, so take time to pull every rope you can see before moving on.
Mission A-3: Portrait ghost: The Polterpup
The Polterpup is the first named ghost and the one that explains the boss capture loop. The Polterpup moves around the room in wide arcs, and the safest stun window is the half-second after he stops. Players tend to lose the Polterpup’s heart in the dark, so keep the beam high on his body rather than on the floor. After a few cycles, the heart grows and the capture bar drops, completing the mission.
Gloomy Manor Boos and gems
Gloomy Manor has five Boos, scattered across the entrance hall, the upper floor, and the basement. The Dark-Light Device reveals them on walls and behind picture frames. Five gems are also hidden in this mansion. The most commonly missed gem is the one inside the grandfather clock on the second floor, which only appears when the clock’s hands are pulled with the suction shot. The basement gem is the easiest to forget because it requires Luigi to vacuum a small, easy-to-miss piece of luggage that reveals a hidden compartment.
Haunted Towers: walkthrough for all missions
Haunted Towers is where the Luigi’s Mansion 2 walkthrough starts to feel like a real puzzle. The For additional context, mansion has more vertical space than Gloomy Manor, more possessed objects, and a stronger emphasis on pulling ropes and chains to change the room layout.
Mission B-1: Cold Case
Cold Case is a chase mission. The mission timer is short, and Luigi has to track a cold-themed portrait ghost through several rooms. The fastest route is to take the elevator to the second floor, sweep the corridor, and then follow the trail of frost down to the kitchen. Players who try to fight every green ghost on the way up lose time, so this is a mission where the timer discipline from the Gloomy Manor pre-mission checklist actually pays off.
Mission B-2: The Fire Elemental
The fire elemental in Haunted Towers is the first true boss in the Luigi’s Mansion 2 walkthrough. The fight is staged around a central candelabra that the elemental uses to spawn flame rings. The safe pattern is to dodge a flame ring, then drag the elemental into the light with a suction shot, stun it, and capture a small amount of progress on the bar. After two full cycles, the elemental will split into smaller flames that each need to be captured individually.
Mission B-3: Portrait ghost: Harsh Possessor
The Harsh Possessor is a possessed suit of armor that jumps between armor stands. The fight has a clear rhythm: stun, capture, wait for the Possessor to retreat to a different stand, repeat. The Luigi’s Mansion 2 walkthrough for this boss is less about raw capture damage and more about reading the stand-switch pattern. Shooting the beam at the next stand before the Possessor arrives is faster than chasing.
Haunted Towers Boos and gems
Haunted Towers has six Boos and six gems. The most easily missed Boo is the one hidden in the chimney of the second-floor study, which only appears when the Dark-Light Device is swept up the wall. The tower’s top-floor gem requires a chain pull that is easy to skip if you are focused on the exit. Plan an extra minute for the gem sweep before heading to the mission exit.
Old Clockworks: walkthrough for all missions
Old Clockworks is the largest mansion in the campaign and the one most likely to break a Luigi’s Mansion 2 walkthrough that has been written from memory. The interior is built around cogs, pendulums, and timed mechanisms, and many rooms require Luigi to wait for the right moment to cross a moving gear or step onto a rising platform.
Mission C-1: Sticky Situation
This mission is the first time Luigi encounters the slime that slows his movement. Slime appears in patches on the floor and walls, and stepping through it drains the heart meter. The Luigi’s Mansion 2 walkthrough here is to scan each room for slime residue with the flashlight, then vacuum it into the Poltergust before crossing. The slime you collect can be deposited into a small dispenser to reveal hidden switches later in the mansion, so do not throw it away at the entrance.
Mission C-2: The Clockwork Castle
The clockwork castle is a sub-area that functions as a giant puzzle box. The Luigi’s Mansion 2 walkthrough for this mission depends on a small handful of mechanical cogs. Pulling the first cog starts the clock tower, which in turn opens a hidden wall in the west wing. The second cog exposes a moving platform that Luigi can ride up to the gem on the second floor. Skipping the second cog is the most common reason players miss a gem here.
Mission C-3: Portrait ghost: Clockwork Soldiers
The Clockwork Soldiers fight is the most mechanically complex boss in the main campaign. The soldiers spawn from toy boxes and the safest approach is to clear a toy box, capture the soldier, then move to the next. The Luigi’s Mansion 2 walkthrough for this boss is the only one in the game that benefits from a Burst cycle to push two soldiers off the central platform. Once the room is clear, the final soldier requires a longer capture and a slow, deliberate tug to bring the bar down to zero.
Old Clockworks Boos and gems
Old Clockworks has seven Boos and seven gems. The basement Boo is the most commonly missed one, since the basement entrance is only revealed after the second cog pull. The gem in the moving-clock room is tied to the same mechanism and is the reward for pulling the cog sequence in the right order.
Secret Mine: walkthrough for all missions
Secret Mine is the first mission set that takes place mostly outdoors, and it changes the Luigi’s Mansion 2 walkthrough in two ways. Visibility is wider than in the mansions, which makes long-range ghosts easier to spot, and the cart-ride sequence at the end of the third mission requires a specific timing pattern to clear without losing a heart.
Mission D-1: Cold Breeze and Warm Hearts
Cold Breeze and Warm Hearts reintroduces the ice-themed ghosts from Haunted Towers but adds a new ghost type that pulls Luigi across the floor with a long tongue. The Luigi’s Mansion 2 walkthrough for this mission is to bait the tongue ghosts into narrow corridors where you can stun them against a wall. Trying to fight them in open spaces is the main reason players run out of hearts here.
Mission D-2: The Mine’s Secret
The Mine’s Secret is a short mission focused on a single sub-area. The Luigi’s Mansion 2 walkthrough entry for this mission is small but easy to fail: the goal is to follow the cart path and vacuum the explosive barrels out of the way before they detonate near Luigi. The barrels respawn after each cart pass, so a slow, patient approach works better than a fast one.
Mission D-3: Portrait ghost: The Ugly Mummy
The Ugly Mummy is a portrait ghost with a very wide hitbox. The Luigi’s Mansion 2 walkthrough for this fight is to dodge the mummy’s lunge, then drag the beam in a slow arc across its body. The mummy’s heart is small, so a long stun is more reliable than a quick one. The cart sequence at the end of the mission is the real test: stay in the cart, vacuum any incoming rocks, and jump to clear the gap at the end of the track.
Secret Mine Boos and gems
Secret Mine has five Boos and five gems. The most missed Boo is the one on the cliff face, which only appears when the Dark-Light Device is swept across the rock wall from the cart path. The most missed gem is the one inside the cart itself, which only appears after the cart-ride sequence is fully cleared for the first time.
Treacherous Mansion: walkthrough for all missions
For additional context, Treacherous Mansion is the late-game mansion, and it is the one the Luigi’s Mansion 2 walkthrough has to handle carefully. The ghost roster is the most diverse, the puzzle rooms are the longest, and the hidden areas are the easiest to overlook. The Dark Moon shard at the end of the mansion is also the most heavily defended.
Mission E-1: Ambush Maneuver
Ambush Maneuver is the first mission where Luigi is ambushed by a small army of green ghosts as soon as the door closes. The Luigi’s Mansion 2 walkthrough for this mission is to retreat to a small side room, thin the group with a Burst cycle, then capture the survivors one at a time. The rewards for clearing the room completely are worth the time investment: a hidden gem and one of the mansion’s harder Boos.
Mission E-2: The Spectral Catch
The Spectral Catch is a fishing-themed sub-mission that uses the Poltergust’s suction shot to pull fish-shaped ghosts out of an indoor pond. The Luigi’s Mansion 2 walkthrough here is to aim low, because the fish ghosts swim near the floor of the pond, and to use the suction shot to pull them into the light. The largest fish is the slowest and is the one that drops the gem for the room.
Mission E-3: Portrait ghost: The Terrible Dog
The Terrible Dog is one of the most aggressive portrait ghosts in the game. The Luigi’s Mansion 2 walkthrough for this fight is to keep moving. The dog charges in a straight line, so a side step dodges the attack and opens a short stun window. The dog retreats to a corner to recover, which is the safest moment to land a capture cycle.
Mission E-4: The Final Shard
The Final Shard is the climax of the Luigi’s Mansion 2 walkthrough. The boss is a large, multi-stage ghost that uses every mechanic from the previous mansions. The first stage is a standard capture cycle. The second stage spawns a small group of green ghosts that need to be cleared with a Burst before the main fight can continue. The third stage requires Luigi to chase the boss around the upper floor of the mansion. The mission timer is tight, so the Luigi’s Mansion 2 walkthrough here is to ignore the remaining Boos and gems and focus on the shard.
Treacherous Mansion Boos and gems
Treacherous Mansion has eight Boos and eight gems, the highest in the game. The post-game mode opens the mansion in a higher difficulty, which rotates the gem locations. A complete Luigi’s Mansion 2 walkthrough for the post-game has to mention that the gem patterns are randomized in the harder modes, so a strategy that worked in a guide video will not necessarily work on a fresh save.
Boss capture patterns at a glance
Because the boss capture cycle in Luigi’s Mansion 2 is so central, a quick reference table is useful for the second or third run. The capture order changes very little across versions, so the same notes apply to both the 3DS original and the HD remaster.
| Boss | Mansion | Best stun window | Capture cycle count |
|---|---|---|---|
| Polterpup | Gloomy Manor | After the dog stops moving | 2-3 |
| Fire Elemental | Haunted Towers | Between flame rings | 3 plus a split phase |
| Harsh Possessor | Haunted Towers | When standing on the active armor stand | 4 |
| Clockwork Soldiers | Old Clockworks | When the toy box is open | 5 including add phases |
| Ugly Mummy | Secret Mine | After the lunge | 4 plus cart phase |
| Terrible Dog | Treacherous Mansion | When the dog is in the corner | 5 |
| Final Shard boss | Treacherous Mansion | After the Burst clear | 6 across three stages |
Post-game content, hidden mansions, and rank rewards
Finishing the campaign unlocks the harder versions of each mansion, plus a small handful of bonus missions. The Luigi’s Mansion 2 walkthrough does not end with the credits, because the rank gates and the new mansion variants are where most of the replay value lives.
Rank gates and how they work
Every mission in the main campaign has a letter grade from D to A, with A being the highest. Higher ranks unlock harder variants of each mansion in the post-game. Reaching a high rank on every mission is the main bottleneck for players who want to clear the post-game Luigi’s Mansion 2 walkthrough.
| Rank | Reward | Strategy to hit it |
|---|---|---|
| D | Default | Just finish the mission with hearts left |
| C | Default | Clear the shard objective without major damage |
| B | Boos and gems become trackable in the lab | Finish the mission with a healthy heart count and a long time buffer |
| A | Unlock the harder version of the mansion in the post-game | Capture every visible ghost, find every gem and Boo, and finish with at least half health and time remaining |
Hidden mansion and challenge modes
Reaching an A rank on every mission unlocks the hidden mansion that closes the post-game Luigi’s Mansion 2 walkthrough. The hidden mansion is shorter than the main campaign but harder, and it locks the player out of any heart restocks between rooms. The challenge mode is the same idea in a more punishing form: the timer is shorter, the heart supply is smaller, and the green ghost count is higher.
Gem and Boo reference for completionists
The gem and Boo totals are the part of the Luigi’s Mansion 2 walkthrough most players come back to. The base numbers per mansion stay the same in the campaign, but the harder mansion variants in the post-game rotate the gem positions. The total count in the table below is the campaign baseline, which is the same on 3DS and on the HD remaster.
| Mansion | Boos | Gems | Portrait ghost |
|---|---|---|---|
| Gloomy Manor | 5 | 5 | Polterpup |
| Haunted Towers | 6 | 6 | Harsh Possessor |
| Old Clockworks | 7 | 7 | Clockwork Soldiers |
| Secret Mine | 5 | 5 | Ugly Mummy |
| Treacherous Mansion | 8 | 8 | Terrible Dog + Final Shard boss |
The Luigi’s Mansion 2 walkthrough for the gem hunt depends on a few universal habits. The Dark-Light Device has to be used on every wall, floor, and ceiling in a room before Luigi leaves. The Poltergust has to be fired at every object that can be picked up, because a small number of gems only appear after a piece of furniture is moved. And every rope, curtain, and chain has to be pulled at least once, because the gem triggers are sometimes tied to those interactions.
Common mistakes that cost time in any mission
Almost every Luigi’s Mansion 2 walkthrough problem comes from a small handful of repeated mistakes. Avoiding them saves far more time than memorizing the perfect route.
- Chasing ghosts away from the light: Stunned ghosts are easier to capture in a well-lit room, so chasing one into a dark corridor usually costs more time than it saves.
- Ignoring the Burst button: The Burst is a panic button, but it is also a tool for thinning a group of ghosts before the main capture cycle starts. Skipping it leads to longer, more chaotic fights.
- Skipping the Dark-Light Device sweep: Boos, gems, and wall messages are easy to miss, and the Dark-Light Device is the only tool that reveals them. The Luigi’s Mansion 2 walkthrough is not a 100% guide without it.
- Forgetting the suction shot on ropes: Many puzzle rooms are gated by a single rope or curtain that has to be pulled to reveal a new path. The Poltergust upgrade is the one that unlocks this ability, so the upgrade mission is the foundation of every later walkthrough.
- Letting the timer run low before the shard: The shard objective is the priority, and most Luigi’s Mansion 2 walkthrough routes save Boos and gems for after the shard is in hand. The timer pressure is real, and chasing a single Boo in the last minute is a frequent reason players miss the A rank.
How the HD remaster changes the walkthrough
The HD remaster of Luigi’s Mansion 2 changes the Luigi’s Mansion 2 walkthrough in three small but meaningful ways. The control mapping uses twin-stick camera and trigger-based actions on modern controllers, which is a real improvement for aiming the beam. The frame rate is higher and the rooms load faster, which means combat is more responsive. And the player can now scan the entire environment with the right stick, which is useful for the rooms that have always required a slow, careful sweep with the Dark-Light Device. None of these changes alter the underlying mission order, but they do shorten the time needed to clear a few of the longest fights, especially the Old Clockworks and Treacherous Mansion bosses.
One thing the HD remaster does not change is the gem and Boo totals. The Luigi’s Mansion 2 walkthrough totals in the table above are the same in both versions, which is part of why the remaster is a faithful port rather than a redesign.
Recommended route through a fresh save
For a player starting a fresh save on either the 3DS original or the HD remaster, the Luigi’s Mansion 2 walkthrough below is the safest first-run order. It assumes the player wants to clear the campaign, hit at least a B rank on every mission, and find the first set of Boos and gems without grinding.
- Gloomy Manor A-1 to A-3: Finish the campaign missions, then sweep the mansion for Boos and gems before moving on.
- Poltergust upgrade mission: The upgrade is the foundation of every later mission, so it should be cleared before the second mansion.
- Haunted Towers B-1 to B-3: Focus on the timer, since the chase mission is the one that gates the B rank.
- Old Clockworks C-1 to C-3: Save time on the cog sequence by reading the wall graffiti before pulling any switches.
- Secret Mine D-1 to D-3: Clear the cart mission last, since the cart sequence is the hardest single challenge in the mansion.
- Treacherous Mansion E-1 to E-4: Hit the A rank on the earlier missions first, because the harder variants of this mansion are the ones the post-game Luigi’s Mansion 2 walkthrough depends on.
Design notes: what the walkthrough teaches about mission pacing
A Luigi’s Mansion 2 walkthrough is also a useful lens for studying mission design, because each mansion is built around a different design constraint. Gloomy Manor is built around the capture cycle. Haunted Towers is built around verticality. Old Clockworks is built around timed mechanisms. Secret Mine is built around visibility. Treacherous Mansion is built around density. The same design pattern is visible in other mission-based games, and the Luigi’s Mansion 2 walkthrough is a small case study in how a campaign can vary a single core loop without ever feeling repetitive.
The reason this matters for a walkthrough is that each mansion is a different design problem. A generalist guide that says “use the flashlight, capture the ghosts, and reach the exit” is technically correct, but it does not help the player who is stuck on the Old Clockworks cog sequence or the Secret Mine cart ride. The mission-specific notes in the walkthrough above are the part of the guide that actually helps when the player is one room away from the Dark Moon shard.
Frequently asked questions
Where is the Dark-Light Device in Luigi’s Mansion 2?
The Dark-Light Device is awarded after a specific mid-game mission in Gloomy Manor, once Luigi has completed the upgrade sequence. From that point on, the device is a permanent part of the loadout and is recharged in the lab between missions. It is the only tool that reveals hidden Boos, wall messages, and a handful of invisible switches in every mansion.
How do I hit the A rank on every mission?
An A rank requires Luigi to finish the mission with at least half of his hearts intact, with time left on the clock, and with most of the side content cleared. In practice, this means capturing every visible ghost, finding at least the obvious Boos, and reaching the exit with a comfortable time buffer. The Luigi’s Mansion 2 walkthrough route above prioritizes the shard objective first, then the Boos and gems, because chasing side content too early is the most common reason for a low rank.
Are the Boos and gems in the same place in the HD remaster?
The campaign gem and Boo locations are identical between the 3DS original and the HD remaster. The harder mansion variants in the post-game rotate the gem positions, so a guide that works for the campaign may not work for the post-game Luigi’s Mansion 2 walkthrough.
What is the hardest boss in the campaign?
The Final Shard boss at the end of Treacherous Mansion is the longest and the most complex fight in the game, but the Clockwork Soldiers fight in Old Clockworks is the most mechanically demanding. The Luigi’s Mansion 2 walkthrough strategy for each is in the dedicated boss section above.
Can I replay a mission to find missed Boos?
Yes. Every mission in the campaign and in the post-game can be replayed from the lab. The Luigi’s Mansion 2 walkthrough recommends keeping a save before the harder missions so that any missed content can be picked up without losing progress.
What does the Burst button actually do?
Burst is a short stroboscopic flash that pushes a group of ghosts back and briefly stuns them. It is the panic button in the heat of a fight, but it is also a useful tool for thinning a crowded room before a long capture cycle. The Luigi’s Mansion 2 walkthrough above recommends using it on the Final Shard boss’s second stage.
Do I need the suction shot upgrade?
Yes. The suction shot upgrade is required for the rope, curtain, and chain interactions that gate several later puzzle rooms. Skipping the upgrade mission is the most common reason a Luigi’s Mansion 2 walkthrough route fails in the second half of the game.
How long does a full Luigi’s Mansion 2 run take?
A first run that focuses only on the campaign usually takes between 12 and 16 hours, depending on the player. A full completionist run that includes the post-game harder mansions, the hidden mansion, and every Boo and gem typically takes 25 to 35 hours. The HD remaster version is a little faster because the higher frame rate shortens a few of the longer boss fights.
What changes in the post-game Luigi’s Mansion 2 walkthrough?
The post-game adds harder variants of every mansion, which rotate the gem and Boo locations, increase the green ghost count, and shorten the mission timer. Reaching an A rank on every campaign mission is the gate for the post-game, and the hidden mansion that closes the post-game Luigi’s Mansion 2 walkthrough is the hardest single challenge in the game.
