Polterguest Rooms are the strangest Exhibits available inTwo Point Museum. These specially-built chambers house ghosts, letting guests observe them while the spirits are unaware that they’re on display. Of course, if the ghosts ever realize that they’re dead, or just get bored, your museum could find itself with a dangerous supernatural situation on its hands.
Polterguest Rooms aren’t as hard to maintain as Aquariums, but the consequences for failing to keep them up to code are much more dire. This guide has everything you need to know about building rooms that will house your deceased guests for eternity.

How Many Ghosts Can A Polterguest Room Hold?
LikeAquariums, the capacity of a Polterguest Room isbased on its size.Each Room can holdone ghost for every five tiles of space that it takes up.This means that the smallest possible Polterguest Room (3x2) can house a single ghost.
Polterguest Rooms don’t need to be squares or rectangles; you canbuild them in Tetris-like shapes to fit your museumas needed.
The majority of Polterguest Roomsdon’t need to hold more than two or three ghosts.The only reason to build one that’s larger would be tosatisfy a Buzz Bonusthat requires a large group all together. A large, crowded Polterguest Room can potentially generate a lot of Buzz and a decent amount of Knowledge, but it’s only worth the footprint if they’re allfully researched and Pristine Quality.
Immersion, Entertainment, And Peace
The ghosts in your Polterguest Rooms need to be keptimmersed and entertained, or they risk breaking out and terrorizing the museum.
Immersion
Immersionis the illusion that the ghost is still alive and experiencing the world as they’re used to it. You can keep a ghost’s Immersion high bymatching the Polterguest Room to their preferred decor type.In general, this will match thetype of ghost that they are; Industrial Age Spirits prefer Industrial Age Decor, Natural Spirits prefer Natural Decor, etc.
Some ghosts will have randomly-generated Traits, like Innkeeper, that change their preferred Decor; be sure to check for these when placing a new arrival!
You can change the Decor of a Polterguest Room from thedrop-down menu in its stat box.This is free, and you can do it as often as you like, but generally you’ll want to pick a theme that fits the tenants and keep to it.
Entertainment
Ghosts are kept entertained byhaving a high Decoration Rating in their Polterguest Room.This is easy to accomplish; justfill the room with Decorations that match the room’s styleuntil it hits level 5. The only thing to consider ismaking sure all the decorations are accessible so that the ghosts can interact with them, andkeeping the door unblocked so that Supernatural Experts can perform maintenance(see below).
If a ghost’s Buzz Bonuses call for it, you canhave one or two Decorations that don’t match the room’s themewithout breaking Immersion. For example, if a ghost wantssomething warmbutno fireplace, consider giving them aLodge Radiatoreven if it’s anachronistic. They won’t mind, and you’ll get more Buzz from the Exhibit.
Peace And Patience
A ghost’s Peace will deteriorate over time,even if their Immersion and Entertainment are maxed out.When it reaches zero, they willbreak free from the Polterguest Roomand start attacking guests. At that point, a Supernatural Expert needs tocapture them and put them back in their room.
A ghost’s Peace degrades much faster if their Immersion and Entertainment needs aren’t met.
Having a Supernatural Expertperiodically visit a Polterguest Room to perform Spirit Maintenancewill restore the Peace of the ghosts inside to full. Your Experts will automatically do this as part of their normal routine, but you may need tomanually assign themif a particular group of spirits are getting unruly.
Each time a ghost breaks free, theylose one point of Patience, indicated by anangry ghost iconon their status screen. When they run out of Patience, theyreturn to the Netherworld permanentlyand can no longer be displayed in your museum.
Tips For Using Polterguest Rooms Effectively
Ghosts are finnicky, and have awide assortment of Buzz Bonuses and Traitsthat can make matching up roommates a tall order. Keep things simple byusing multiple smaller Polterguest Rooms. It’s not perfectly space-efficient, but by building themslightly bigger than they need to beyou can ensure that the inhabitants have plenty of room for Decorations and Entertainment:
1
3x3
2
3x4
3
3x5
Smaller populations meanfewer conflicting needs.
Wailon Lodge has plenty of pre-built Polterguest Rooms that you can customize as needed, but on other maps you’ll need to build to suit. In those cases, where ghosts won’t be the main focus of your museum, it’s best tochoose a Famous Spirit or twoto be your star attraction and build around them. Any ghosts that don’t fit the theme can besold, analyzed, or stored for later.
Building a stellar collection of ghosts to displayrequires frequent trips to the Netherworld, which has some of the game’smost dangerous Expeditions.Have your Workshops build a good supply ofCurse Countersso you always have one ready, and make sure thatat least one of your Supernatural Experts has Survival Skills at Level 2to counter the deadly Hellhole-d Event.
