Our setting is the Last Resort hotel. Luigi and friends were invited to this luxurious hotel, but it turned out to be a trap set by his nemesis, King Boo.
The dazzling resort transforms into a massive, haunted hotel overnight, and Mario, Peach, and Toad get captured by King Boo.

In order to rescue Mario and the others, Luigi gets help from the indispensable ghost-busting Poltergust G-00, its inventor Professor E. Gadd, and his trusty pal Polterpup to explore the hotel.

While solving the heap of puzzles in the dim hotel and defeating the quirky ghosts he meets along the way, Luigi aims for the top floor where King Boo awaits.

To make your way through the hotel steeped in mysteries due to all of these ghostly tricks, you'll need to master the various functions of the Poltergust G-00.

Let's take a look at the basic features of the Poltergust G-00 to make sure you're fully prepared!

Shine the Strobulb on anything suspicious

There is a light attached to the end of the Poltergust G-00 that will allow you to light the way inside the dim hotel.

Press the A Button (or R Button), and you'll be able to shine the powerful light of the Strobulb. Hold the A (or R) Button longer to light up an even wider area.
If you see something fishy, try shining the Strobulb's light on it.

Use the vacuuming and blowing away functions to move anything that catches your eye

The Poltergust G-00 is a vacuum-like device that can suck up most objects.
If something catches your eye, press and hold the ZR Button and try to suck it up. You might find a hidden item or even activate something!

But do note that you might not be able to suck up objects that are too large. If that happens, press the ZL Button to use your blowing power to smash whatever you sucked up.

You can also use the wind created by vacuuming and blowing away to do things like turn handles or propellers.

Shine your Dark Light to break curses

If you press and hold the X Button, you can shine the special Dark Light used for breaking curses.
If you shine your Dark Light on unusual places, such as areas that seem empty even though there is something in a mirror's reflection, for instance, things that have been hidden from your sight may emerge.

If you continue to shine your Dark Light, the object will release cursed Spirit Balls.
If you suck all of these up, you'll be able to remove the curse placed on that object and bring it back to normal.

You can even use the Dark Light to free anything trapped in a picture frame.
This means you can save your friends that have been trapped inside of picture frames. What a relief!

Use Burst to blow away anything that stands in your way

Press the ZR and ZL Buttons simultaneously to release a jet of air and blow away all of the objects around you with a Burst. You can also use the wind power from this move to jump just a little bit.

If you want to break something, fire off a Suction Shot

The Poltergust G-00 also comes equipped with a Suction Shot.
You can use the Y Button (or L Button) to fire a rubber plunger and stick it to a flat, smooth surface.

The plunger has a rope attached. Suck it up with the Poltergust G-00 and then press the A Button, and you'll be able to forcefully slam whatever you've sucked up and break it.
This can be effective on objects that can't be moved using Burst, so give it a shot whenever you're feeling stuck.

When you can't do it alone, call on your buddy, Gooigi

The Poltergust G-00 is equipped with a green doppelganger named Gooigi, who looks just like Luigi. You can summon Gooigi by pressing down on the Right Stick, after which you can move him around freely.

Gooigi is quite literally a softie, so he can squish into narrow gaps such as vents or drains, and even pass by iron bars and dangerous traps.

You can switch between controlling Luigi and Gooigi by pressing down on the Right Stick.
Since whichever character you're not controlling will automatically continue to move, if you use this wisely, you can move both characters at the same time for a short period.

Additionally, in Co-Op mode, where you can play together with friends or family, one of you can control Luigi while the other controls Gooigi, letting you play the game together.

Gooigi is a reliable friend, but his weakness is that water makes him dissolve. Make detours around any areas with water and switch between Gooigi and Luigi to make your way deeper into the hotel.

You'll encounter plenty of ghosts while exploring the hotel, but don't worry. You have the Poltergust G-00. Let's go over how you can get rid of these ghosts.

Shine the Strobulb to stop them in their tracks

Ghosts do not like light. If you shine the Poltergust G-00's Strobulb on them, you'll surprise them, stopping them in their tracks.

If there are many ghosts around, press and hold the A Button to charge the Strobulb before you shine it.
Once charged, you'll be able to light up a wider area so that you can stop multiple ghosts at the same time.

Suck up ghosts to catch them

Once you manage to shine the Strobulb and stop the ghost, you have a chance to catch them.
Press and hold the ZR Button to get suction on the ghost, and then keep pressing the ZR Button to vacuum it up.

When vacuuming, you'll need to pull in the opposite direction the ghost is trying to run to wear down its HP.
You'll wear down the ghost's HP bit by bit as it tries to escape, and when its HP reaches zero, you can suck it into the Poltergust G-00 and capture it.

Slam ghosts into the ground to deal serious damage

The ghost may get away from you while you're trying to suck it up and wear down its HP.
When that happens, Slam, which slams ghosts and deals a large amount of damage, will be of use.

A gauge will appear above Luigi as you're sucking up a ghost, so when that fills up, press the A Button to hit it with Slam.
You can also continually deal damage every time you press the A Button until your gauge is empty!

You can also use Slam to attack multiple ghosts around you. Use Slam to smash the ghost in your grasp into other ghosts and deal damage to all of them at once.

There are some ghosts that come at you only in particular areas or by using odd attacks.
But there's no need to panic! Use the Poltergust G-00 to handle the situation; no sweat.

When you can't dodge ghostly attacks, blow them away with Burst

If you find yourself surrounded by ghosts in a cramped space or just unable to avoid an attack, use Burst to blow them away and reposition yourself.

When a ghost uses ground attacks, hop over it with a Burst

Some ghosts attack from a distance. For shockwaves and other attacks that travel along the ground, use Burst to jump over them and dodge.

Blow away whatever a ghost has using Burst

When ghosts are wearing glasses or carrying luggage, they will use these to block the light of your Strobulb. First, try using Burst to blow away their items and then shine the Strobulb on them.

If you can't blow it away, break it with a Suction Shot

There are some objects that ghosts will have that can't be blown away using Burst. If this happens, try using Suction Shot.

When you can't beat a ghost, bring in backup with Gooigi

Even though Gooigi has less HP than Luigi, he can come back right away after being defeated.
When you encounter a tough ghost, it can help to fight it with Gooigi first to get used to its attacks.

Also, if you really can't take down a ghost, we recommend playing with friends or family to beat it together! If you work together in Co-Op mode, even the spookiest of ghosts will be a piece of cake.

With the above, you've hopefully learned how to solve puzzles and fight ghosts using the handy Poltergust G-00 item in Luigi's Mansion 3.

Although you might feel uneasy exploring the dark, eerie hotel, as long as you know the tricks to bust these spectral spooks, there's no need to be more scared than necessary!
You might even start really looking forward to seeing what kind of quirky ghosts you'll meet next!
