Suck up a large stack of money behind the left pillar (approx. 100 Coins). Run into cones near the entrance for about 30 Coins. Stun passing Rats for potential Coins. Suck up a sheet-covered car near the right-most pillar, flash the green button on the trunk to reveal and collect the Clear Gem. Clear a pile of dirt for a few Coins. Clear another pile in the far-left corner (approx. 30 Coins). Suck up a rathole in the lower-left corner (5 Coins). Collect Bills from a shelf above the rathole. Move tires near the rathole for more Coins. Go up the stairs to find a toolbox with approx. 30 Coins. Note a locked area with a Red Gem, which is inaccessible for now.

Walkthrough
Your ultimate guide to Luigi's Mansion 3! We cover 100% of the game, from story progression and collectibles like gems and Boos to achievements and earning an A Rank. Let's explore The Last Resort!
Hey there! Welcome to my Luigi's Mansion 3 guide. I've put this together to make exploring The Last Resort hotel as smooth as possible, with each floor getting its own chapter. Since the first couple of floors involve a lot of back-and-forth, they don't have specific floor numbers in their titles.
This guide is all about helping you achieve 100% completion. That means we'll be hunting down every single thing in the hotel – from the do-or-die elevator buttons that move the story forward, to all the hidden collectibles like gems and Boos, and grabbing as much cash as possible to snag that sweet A Rank at the end. Plus, we'll tackle all the achievements along the way. If you're a completionist like me, you're going to love this!
If you're just trying to get past a tricky puzzle or boss and need a quick fix, just hop to the chapter for the floor you're on and use your map to find the exact room. Hopefully, you'll find the solution you need in a flash. For those hunting for a specific gem, keep an eye out for text highlighted in blue. Missing Boos? Look for purple text. I've also color-coded Boss Battles in yellow and regular enemy encounters in green to make things a bit more visually interesting. Pretty neat, huh?
Alright, let's get this guide rolling and dive into the spooky fun. Enjoy!
| Note If you find a spot with Gold in the game that I didn't mention in the guide, please go ahead and leave a comment with the missing treasure spot so I can add it to the guide, or contact me on Reddit at Zedamaniac16, that would actually be better. Furthermore, if you wish for me to make Side Quest guides for the Gems, Boos, and Achievements, let me know and I'll be sure to create those guides if the opinion is popular. I also have plans on creating a Video Walkthrough to go with this guide, perhaps even add some images, as well as input some boxes designed to give some information on characters and enemies throughout the walkthrough. If this guide is successful and the idea is intriguing to some of you, I'll be sure to do it as well! |
| ScareScraper Note There are some achievements to accomplish through playing ScareScraper, which I will not go through in the walkthrough. Playing this mode by yourself can be quite a challenge, perhaps even impossible, so grab a friend and start grinding for the last achievements. These are: - "Cleared the 5-floor ScareScraper" achievement - "Cleared the 10-floor ScareScraper" achievement - "Defeated 40 rare ghosts in ScareScraper" achievement - "Revived teammates 20 times in ScareScarper" achievement - "Completed 100 total floors in Scarescraper" achievement - "Defeated Boolossus 20 times in Scarescraper" achievement These are all fairly simple achievements to understand, so good luck on this new adventure in ScareScraper. |
